Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

Fay automatic lathe, 1921. [1] Bullard Mult-Au-Matic, a vertical, multispindle automatic lathe, 1914. [2] In metalworking and woodworking, an automatic lathe is a lathe with an automatically controlled cutting process. Automatic lathes were first developed in the 1870s and were mechanically controlled.
This system is a typical plane often seen in mathematics when graphing. This system is required to map out the machine tool paths and any other kind of actions that need to happen in a specific coordinate. Absolute coordinates are what are generally used more commonly for machines and represent the (0,0,0) point on the plane.

Canned cycles automate certain machining functions such as drilling, boring, threading, pocketing, etc... [1] Canned cycles are so called because they allow a concise way to program a machine to produce a feature of a part. [2] A canned cycle is also known as a fixed cycle. A canned cycle is usually permanently stored as a pre-program in the ...
SFM is a combination of diameter and the velocity of the material measured in feet-per-minute as the spindle of a milling machine or lathe. 1 SFM equals 0.00508 surface meter per second (meter per second, or m/s, is the SI unit of speed). The faster the spindle turns, and/or the larger the diameter, the higher the SFM.
In metrology and the fields that it serves (such as manufacturing, machining, and engineering), total indicator reading (TIR), also known by the newer name full indicator movement (FIM), is the difference between the maximum and minimum measurements (the range), that is, readings of an indicator, on the planar, cylindrical, or contoured surface ...
