Abstract
The author presents the technique of calculated evaluation of processing errors arising from thermal deformations during the blank part and cutting tool processing. The assigned task was solved using the dimensionless groups of cutting process which consider process conditions, such as: cutting mode (cutting speed, feed motion and cutting depth), tool cutting part geometry (face and clearance angles, plan root radius, cutting edge rounding-off radius), mechanical and physical and thermophysical properties of processed and tool materials (flow shear resistance of processed material, heat conduction of processed and tool materials, temperature linear expansion factors of processed and tool materials).
Theoretical dependences allowed getting the numerical values of errors arising from thermal deformations of a blank part and the cutting tool. It allowed evaluating the efficiency of feed, cutting speed and other cutting process parameters.
When evaluating errors arising from thermal deformation of cutting tool, the author considered heat transfer to the external environment through the cutting tool side face.
When getting theoretical dependences for evaluation of processing errors, the author used the dependences for evaluation of temperature in the cutting area and its expansion within the blank part and cutting tool got by the Professors S.S. Silin, A.N. Reznikov, A.V. Lykov and others.
The comparison of values of processing errors arising from thermal deformation of processed blank part and cutting tool showed their close agreement that is quite acceptable for practical purposes.
