#### Turning Speeds and Feeds and Depth of Cut

• Reference
• Technology of Machine Tools, 7th Ed by Krar, Gill, Smid
• Material is 1“ round, material Aluminum
• Step 1 - Lookup Cutting Speed (CS) feet/min of a material
• “Lathe work cutting speed (CS) may be defined as the rate at which a point on the work circumference travels past the cutting tool.” (ibid, p. 370)
• Aluminum
• Rough Cut: 200 ft/min
• Finish Cut: 300 ft/min
Lathe Cutting Speed (CS) feet per min (ft/min) for various materials
Material Turning and Boring - Rough Cut Turning and Boring - Finish Cut Threading
Aluminum 1060 Alloy 200 300 60
Delrin
Steel AISI 1020 90 100 35
• Step 2 - calculate RPM or lathe spindle speed in revolutions per minute (r/min)
• RPM = CS * 4 / D = 200 * 4 / 1 = 800 RPM which is too fast, take 1/3 of this = 266 RPM
• CS = 200 ft/min for Aluminum
• D = Diameter in inches
• Step 3 - lathe feed controlled by the gearbox
• distance the cutting tool advances along the length of the work for every revolution of the spindle
• Aluminum
• Rough Cut: 0.015 - 0.030 inches
• Finish Cut: 0.005 - 0.010 inches
• Step 4 - depth of cut
• the tool feed is radius and the material removed is diameter
• If I need to remove 0.010” of material, then depth of cut is 0.005“
• Aluminum
• Finish Cut: 0.005 -

#### Turning Speeds and Feeds

• How do I determine the cut time (minutes)?
• cut time = cut length / feed rate (IPM)
• How do I determine the feed rate (IPM)?
• feed rate = spindle speed (RPM) x cutting feed (IPR)
• How do I determine the cutting feed (IPR, inches per revolution)?
• the distance that the cutting tool or workpiece advances during one revolution of the spindle
• ipm = feed rate (inches per minute)
• ipr = cutting feed (inches per revolution)
• rpm = spindle speed (revolutions per minute)
• fpm = cutting speed (feet per minute)
• sfm = cutting speed (surface feet per minute)
• CS = cutting speed (older notation)
• too low cutting speed (SFM or CS) produces discontinuous chips (BAD)
• proper cutting speed (SFM or CS) produces continuous chips (GOOD)
• too high cutting speed (SFM or CS) produces built up chips (VERY BAD)
• Step 1 - lookup the surface feet per minute (SFM) for the material cutting on the lathe. What is your speed? respond with SFM not RPM
• SFM - also called surface speed or simply speed is the speed difference (relative velocity) between the cutting tool and the surface of the workpiece it is operating on. It is expressed in units of distance along the workpiece surface per unit of time, typically surface feet per minute (sfm). (Destiny Tool - Understanding Speeds & Feeds)
• Step 2 - find diameter of rotating part/tool. If drilling, use diameter of drill bit. If on the lathe, use diameter of workpiece. If on the mill, use diameter of cutter tool.
• rough cut 0.001” any deeper will cause chatter
• finishing cut 0.0002“ for accuracy and finish
• see CNC Cookbook G-Wizard
• Step 3 - calculate max RPM (THATLAZYMACHINIST recommends using 1/3 of max RPM)
• actual max RPM = SFM x 3.82 / D
• actual max RPM = SFM x 12 / (π x D)
• 12 / π = 3.8197
• estimated max RPM = SFM x 4 / D
• Step 2 - calculate the feed rate (IPR, inches per revolution)
• Step 2 - desired cut diameter in inches of workpiece
• Definition of cutting speed
• feet per minute (fpm)
• surface feet per minute (sfm)
• Definition of feed or feed rate, f the speed of the cutting tool's movement relative to the workpiece as the tool makes a cut
• The feed rate is measured in inches per minute (IPM)
• inches per revolution (ipr)
• Calculating the RPM
• spindle speed (rpm)
• Identification of the RPM formula
• Calculating the number of revolutions needed to move a lathe tool a given distance when given the feed per revolution
• Time required to make one cut over a given length when given the RPM and feed per revolution
• Calculating the RPM of a given drill diameter when drilling on a lathe
• What about Material Removal Rate (MRR)? Seems like a balance, more material you remove the more wear and tear on equipment.

## How to make these parts

• How would I make a flange? Allied Group Flanges has several flanges that can be purchased. When I made a flange, the hole pattern only fit in one setting, that is if I rotate the flange, then the holes didn't line up. This is due to the difficulty of laying out the pattern and the drill bit on the drill press wandering a little bit.

### Circular Hole Layout

• “A very practical use for this kind of calculation is in spacing bolt holes or otherwise dividing a circle into any number of equal parts. It is easy enough to get the length of each arc of the circumference by dividing 360° by the number of divisions, but what we want is to find the chord or the distance from one point to the next in a straight line as a pair of dividers would step it off. First divide 360° by the number of divisions - say 9 - and get 40° in each part. Fig. 5 shows this and we want the distance shown or the chord of the angle. This equals twice the sine of half the angle. Half the angle is 20° and the sine for this is 0.342. Twice this or 0.684 is the chord of the 40° angle for every inch of radius. If the circle is 14 inches in diameter the distance between the holes will be 7 times 0.684 or 4.788 inches. This is very quick and the most accurate method known.” (American Machinists' Handbook, 2nd Edition, by Fred H. Colvin and Frank A. Stanley, p. 523)

## Metal Characteristics

### Ferrous (containing Iron, Fe)

#### Cast Iron

• Malleable Iron - can be hammered into shape without fracturing
• Use carbide cutting tools when working with Iron, Fe
• Don't use cutting fluids on cast iron, use compressed air if a coolant is needed

## Measurements

### Micrometer

• How to read an inch micrometer by ET Prof - excellent discussion on micrometer

### Finding Center

• “Centering Parts to be Turned.As previously mentioned, there are a number of different methods of forming center-holes in the ends of parts that have to be turned while held between lathe centers. A method of centering light work, and one that requires few special tools, is first to locate a central point on the end and then drill and ream the center-hole by using the lathe itself. Hermaphrodite dividers are useful for finding the center, as illustrated at A, Fig. 25, but if the work is fairly round, a center-square B is preferable. A line is scribed across the end and then another line at right angles to the first by changing the position of the square; the intersection of these two lines will be the center, which should be marked by striking29 a pointed punch C with a hammer. If a cup or bell center-punch D is available, it will not be necessary to first make center lines, as the conical part shown locates the punch in a central position. This style of punch should only be used on work which is fairly round.” (Turning and Boring by Franklin D. Jones, p. 29)

### Measure Diameter

• Toms Techniques - Common Methods of Measuring the Diameter of a Hole
1. Drill Bits
2. Inside Calipers - transfer to micrometer to measure
3. Telescoping Gauge Set from Harbor Freight - transfer to micrometer to measure

• Identify bolt size, screw thread form, external or internal threads, TPI and class. For example:
• 1/2” bolt diameter
• 13 Threads Per Inch (TPI)
• Class of Fit
• Class 1A (external) and 1B (internal)
• Loose fit between mating threads, ideal for quick assembly and disassembly, where speed is more important than precision. This class is seldom used.
• Class 2A and 2B
• ideal for general assembly fasteners and is the most common class of fit found on general-purpose nuts and bolts. Easy to assemble and still offer enough thread engagement to achieve considerable strength.
• Class 3A and 3B
• has little or no clearance between mating threads, used when a very accurate or high-strength assembly is required. This class of fit is more expensive to achieve since its production must be monitored closely in order to ensure accuracy. (Precision Machining Technology, p. 417)
• Step 0 - prepare workpiece by facing and turning and countersink ends with a center drill
• Step 1 - determine finish diameter of the work piece/bolt, threads per inch, and
• Step 2 - determine threads per inch (TPI)
• Step 3 - Machinery Handbook
• Major diameter (used turn workpiece to this diameter range)
• Minor diameter (used to determine depth of cut for the thread and thread relief groove or undercut)
• Depth of cut is Major - Minor diameter (don't be confused with radius or diameter, lathe manufactures understand you can't cut a radius on the lathe, only can cut diameter so the dial dimensions are for diameters)
• Step 4 - face workpiece and if going to use the tail stock to hold the workpiece, add center drill
• Step 5 - turn workpiece to within major diameter range
• Step 6 - cut thread relief groove/undercut to the minor diameter
• Step 7 - lathe - change gears to required TPI and reduce spindle RPM speed to 1/4 turning speed around 70 RPM for mild steel.
• Step 8 - rotate compound rest in-feed to 29-29.5 degrees. Both cross slide and compound set to 0. Use center/fishtail gage to verify 60 degree angle of cutting tool and proper alignment with workpiece.
• Step 9 - paint layout fluid (Dykem) on workpiece, touch off work piece and do a very light pass (0.001“). Use thread gage to measure markings.
• engage half-nut lever at the same number to avoid problems
• “Usually, even-number threads per inch can be cut by engaging the half-nut lever at any number on the thread dial, and odd-number threads per inch are cut by engaging the half-nut lever at the odd numbers on the dial.” (Precision Machining Technology, p. 425)
• MSC Direct screw pitch gage
• Step 10 - depth of cut = compound-rest distance x cos 30 degrees, 0.010” cos 30 = 0.00866“
• Benefits of using compound rest
• cut only on one side of the bit
• faster - only have to advance the compound-rest, don't have to worry about DRO, just turn cross feed out one full turn, move carriage back to start of the thread, advance cross fee back in one full turn, then advance compound rest 0.02” to make another pass on the threads
• Disadvantage - have to calculate the thread depth using cos 30 degrees
• Formula to calculate the depth of thread, d see Machinery's Handbook 27th Edition, p. 1725
• Step 11 - measure pitch diameter
• Step 12 - screw on nut

• Irwin Tools. Tubalcain recommends HSS (High Speed Steel) taps instead of carbon steel (cheaper). Cannot sharpen taps so trash if dull.
• Tap Blocks
• How to layout, drill and tap a hole using a drill press by www.lewisrazors.com
• Ways to tap a hole straight - Part A by Lyle Peterson (a.k.a tubal cain or MrPete222, recommends using a counter bore about half way through the material with a larger drill bit, for example he used a tapper tape (7-8 tapper teeth) instead of a plug tap (3-4 tapper teeth), use cutting oil, turn about one full turn of the tap, then back it off, 5/16-18 threads per inch, then use a 1/4“ drill bit for the entire hole, then counter bore with 5/16” about halfway down. This helps the tap to start straight. Also shows how to use a Tap Handle Level from Edge Technology Products.com. Also shows the hand tapper guide. Lastly, using a homemade circular guide block

## Band Saw

• Cutting 1 inch solid round of ASTM A36 steel with 10/14 blade and 200 fpm, took 2 min 30 sec to complete.
• Speed 200 fpm (feet per minute), cut/feed rate = 1.27 in2/min
• From Machinery's Handbook, Material Steel (A36 Shapes) use 270 fpm
• 64-1/2 in. x 1/2 in. Supercut Bandsaw Blade bimetal bandsaw blade 10-14 teeth per inch, cost \28 for one blade • “The size and character of the chips being produced are the best indicators of the correct feed force. Chips that are curly, silvery, and warm indicate the best feed rate, the band speed, or both. If the chips are thin or powdery, the feed rate is too low, so increase the feed rate or reduce the band speed.” (Machinery's Handbook 27th Edition, p. 1140) • “The tooth selection chart above is a guide to help determine the best blade pitch for a particular job. The tooth specifications in the chart are standard variable-pitch blade sizes as specified by the Hack and Band Saw Association. The variable-pitch blades listed are designated by two numbers that refer to the approximate maximum and minimum tooth pitch. A /6 blade, for example, has a maximum tooth spacing of approximately 1/4 inch and a minimum tooth spacing of about 1/6 inch…. To use the chart, locate the length of cut in inches on the outside circle of the table (for millimeters use the inside circle) and then find the tooth specification that aligns with the length, on the ring corresponding to the material shape. The length of cut is the distance that any tooth of the blade is in contact with the work as it passes once through the cut. For cutting solid round stock, use the diameter as the length of cut and select a blade from the ring with the solid circle. When cutting angles, channels, I-beams, tubular pieces, pipe, and hollow or irregular shapes, the length of cut is found by dividing the cross-sectional area of the cut by the distance the blade needs to travel to finish the cut. Locate the length of cut on the outer ring (inner ring for mm) and select a blade from the ring marked with the angle, I-beam, and pipe sections.” (Machinery's Handbook 27th Edition, p. 1138) • “Example: A 4-inch pipe with a 3-inch inside diameter is to be cut. Select a variable pitch blade for cutting this material.\\The area of the pipe is p/4 x (42 - 32) = 5.5 in.2 The blade has to travel 4 inches to cut through the pipe, so the average length of cut is 5.5/4 = 1.4 inches. On the tooth selection wheel, estimate the location of 1.4 inches on the outer ring, and read the tooth specification from the ring marked with the pipe, angle, and I-beam symbols. The chart indicates that a 4/6 variable pitch blade is the preferred blade for this cut.” (Machinery's Handbook 27th Edition, p. 1138-9) ## Milling • “In Fig. 109, E represents a view of the face of a milling cutter, and F a sectional view of the same, while G represents a piece of work passing under the cutter and not between the cutters, as shown in the case of the work D. The arrow H denotes the direction in which the cutter E would require to revolve, and the arrow I the direction in which, in that case, the work would require to travel; from which it will be perceived that the lateral strain placed upon the work by the cut is in a direction to force the work back from the cutter, and this must always, in the use of milling-tools, be the case, and is a very important consideration for the following reasons: From the breadth of cut taken by a milling-tool, and from the acute angle at which the teeth of the cutter strike the cut when the work passes below the circumference of the cutter, the strain due to the cut is immense; and were this strain in a direction to drag or draw the work below or towards the cutter, the latter would, from the spring of the spindle, rip into the work and tear its own teeth off.” (Complete Practical Machinist, The: Embracing Lathe Work by Joshua Rose,p. 304) • “Thus, in Fig. 111, suppose A to be a milling-cutter revolving in the direction of the arrow B, and C to be a piece of work travelling in the direction of D, it will be readily perceived that there will be an enormous strain in a direction to force the work from its chuck or clamps and drag it under the cutter.” (Complete Practical Machinist, The: Embracing Lathe Work by Joshua Rose, p. 304) • Vintage Machinery Keith Rucker - Machine Shop Basics: Setting up a Vise on a Milling Machine ### Sine Plate ## Lathe • Quick Change Tool Post ### Crankshaft • Tailstock traverse (x-axis) adjustment is typically ±0.5” ### Sherline Lathe ### Lathe Purpose • The lathe only produces three types of cuts, which cuts can then be used for drilling, cutting tapers, threading, grinding, plunge cuts (parting) 1. Turning - cutting tool is moved parallel to the lathe axis, removes material from the outside diameter of the work piece 2. Facing - cutting tool is moved perpendicular to the lathe axis, removes material from the end or edge of the part 3. Boring - cutting tool removes material from the inside diameter of the work piece #### Select Cutting Conditions 1. select depth of cut 2. select feed rate (inches per revolution, ipr) 3. select cutting speed (feet per minute, fpm or surface feet per minute, sfm) 4. calculate spindle speed (revolutions per minute, rpm) #### Turning • Turning tool bits - AR, AL, BR, BL, TE where R is right and L is left. Letter A and B designate the angles of the cutting edge. Mini Lathe Users Guide • TAR = T indicates that it holds triangular inserts, A indicates the insert has a zero degree side angle, R indicates right hand tool (i.e. right hand tools cut from right to left). See LittleMachineShop.com Chris Tips • TAL = T indicates that it holds triangular inserts, • TBR = T indicates that it holds triangular inserts, B indicates the insert has a 15° side angle, R indicates right hand tool • TBL = T indicates that it holds triangular inserts, B indicates the insert has a 15° side angle, L indicates left hand tool (cut from left to right) • TE = T indicates that it holds triangular inserts, E indicates the insert has a 30° side angle. In other words, the point is centered. ##### Radius/Direct Reading vs Diameter/Actual Reading • Example of Radius Reading, if you feed in 0.010“ via the cross feed, you will remove 0.020” of material. #### Facing #### Parting/Cut-Off or Plunge Cuts • “Parting is the process of cutting off a piece of stock while it is being held in the lathe. This process uses a specially shaped tool bit with a cutting edge similar to that of a square-nosed tool bit. When parting, be sure to use plenty of coolant, such as sulfurized cutting oil (machine cast iron dry). Parting tools normally have a 5° side rake and no back rack angles. The blades are sharpened by grinding the ends only. Parting is used to cut off stock, such as tubing, that is impractical to saw off with a power hacksaw. Parting is also used to cut off work after other machining operations have been completed (Figure 7-59). Parting tools can be of the forged type, inserted blade type, or ground from a standard tool blank. In order for the tool to have maximum strength, the length of the cutting portion of the blade should extend only enough to be slightly longer than half of the workpiece diameter (able to reach the center of the work). <b>Never attempt to part while the work is mounted between centers</b>. Work that is to be parted should be held rigidly in a chuck or collet, with the area to be parted as close to the holding device as possible. Always make the parting cut at a right angle to the centerline of the work. Feed the tool bit into the revolving work with the cross slide until the tool completely severs the work. Speeds for parting should be about half that used for straight turning. Feeds should be light but continuous. If chatter occurs, decrease the feed and speed, and check for loose lathe parts or a loose setup. The parting tool should be positioned at center height unless cutting a piece that is over 1-inch thick. Thick pieces should have the cutting tool just slightly above center to account for the stronger torque involved in parting. The length of the portion to be cut off can be measured by using the micrometer carriage stop or by using layout lines scribed on the workpiece. Always have the carriage locked down to the bed to reduce vibration and chatter. <b>Never try to catch the cutoff part in the hand; it will be hot and could burn.</b>” (Fundamentals of Machine Tools, US Army TC 9-524, p. 7-33) • Tips • Make sure the parting tool is square/perpendicular to the part, if not, will bind and break the part or tool. • Tubal Cain's Machine Shop Tips 35 - Part 1: Parting on the Lathe • Tubal Cain's Machine Shop Tips 36 - Part 2: Parting on the Lathe • Tubal Cain's Machine Shop Tips 37 - Part 3: Parting on the Lathe - using ISCAR cut off tool • Tubal Cain's Machine Shop Tips 37 - Part 4: Parting on the Lathe - brass plumb bob and Popular Mechanics Nov 1944 • Tom's Techniques - Common Sense Machining - Parting on the Lathe #### Slotting #### Boring ##### Cylinder Hone #### Knurling • “Knurling is not strictly a machining operation as no metal is cut. It is rather a forming operation in that hard patterned knurls are pressed into work, depressing and raising the surface of the metal into the knurl pattern. As with all other forming operations, the work can be no better than the pattern-your knurling no better than your knurls. Be sure that knurls are sharp and clean-cut (preferably hob-cut) and properly hardened. Since to make a true uniform knurling the pressure on both knurls must be uniform, select a knurling tool that is self-centering, that automatically equalizes the pressure on the knurls and has sufficient strength to withstand the terrific end and side thrusts encountered in this operation.” (The Care and Operation of a Lathe by Sheldon Machine Co., Inc., p. 80-81) • “Before starting to knurl, remove the work from the lathe and scribe lines indicating the part to knurled. In knurling, the back gears must be used and the lathe operated at slowest back-geared speed for best results. Always engage the back gears while the lathe is idle (never when it is running as this can strip the gears). (The Care and Operation of a Lathe by Sheldon Machine Co., Inc., p. 80-81) • “Knurling exerts extreme thrust against centers and bearings. This thrust can be materially lessened if the knurling tool is fed to the work at a slight angle off from perpendicular to the line of the work, so that the right side of the knurl engages the work first.” (The Care and Operation of a Lathe by Sheldon Machine Co., Inc., p. 80-81) #### Winding Coils • Making Springs on a Lathe by Dean Williams • How to Wind a Coil Spring on the Metal Lathe by Toms Techniques • To maintain tension on the spring wire, try install a clamp at the mandrel, where the wire enters.

1. Lathe only produces three types of cuts:
1. Turning - cutting tool is moved parallel to the lathe axis, removes material from the outside diameter of the work piece
2. Facing - cutting tool is moved perpendicular to the lathe axis, removes material from the end or edge of the part
3. Boring - cutting tool removes material from the inside diameter of the work piece
4. These cuts can then be used for drilling, cutting tapers, threading, grinding, plunge cuts
