Abstract : Experiments and calculations have shown that, during machining of specimens with straight cut-off tools, the principal factor affecting the magnitude of the overall temperature error is the temperature error due to the elongation of the cutting tool. For accurate work the cutting tool length should be minimized. With increased cutting speed and feed rate the temperature of the part decreases; however, the total accompanying thermal deformation is much greater than the decreased thermal deformation of the part.
