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
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)
    • Figure 1-0 Chip Types
  • 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)
    • Figure 1-0 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)

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)

  • Figure 1-0 Band Saw Blade Tooth Selection by Ellis Manufacturing Company, Inc
  • “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)
  • Figure 1-0
  • Figure 1-0 Band Saw Blade Selection, Machinery's Handbook 27th Edition, p. 1138
    • “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)


  • “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)

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

Radius/Direct Reading vs Diameter/Actual Reading


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)

  • Figure 2-0 Knurl example in plans - Fundamentals of Modern Drafting by Paul Ross Wallach, p. 326
  • Figure 1-0 How to Run a Lathe, for the Beginner by South Bend Lathe, p. 26
  • “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)
