ANALYSIS CONDITIONS FOR RELIABLE ATTACH OF WORKPIECES DURING LATHE MACHINING ON THE MASHINES WITH NUMERICAL SOFT-WARE CONTROL

Abstract

In the article the conditions are properly secured work pieces when turning on CNC machines. The mathematical expressions that guarantee no damage while fixing in the chuck work pieces of ductile and brittle materials. Expressions allow determining the minimum length of the fastening pieces in the cartridge for these materials, as well as for the calculation of permissible cutting forces. It is shown that by adjusting the processing conditions may prevent damage to the work piece surfaces at the impossibility of changing their length in the fixing chuck.
