Layer can be used to remove machining allowance during the processing of floor boring and milling machine.

When we are in the ground boring and milling machine processing, in the process of removing the allowance, the design of cutting sequence and tool path is a very important step, parts in the cutting process, the balance state of residual stress is destroyed, reasonable cutting sequence and tool path will make the residual stress gradually uniform change. When after the completion of the mechanical parts processing, the residual stresses in the balance, parts will not produce large deformation, so when the ground boring and milling machine processing, need reasonable arrange the processing times, the various surfaces of the part and the order of surface of reasonable arrangement, each cutting tool feeding direction and tool feed, exit the direction, And these contents will be marked in the machining process procedures.

The cutting sequence and cutting path of each surface of large size parts: layer can be used to remove machining allowance. In the process of turning the inner and outer surface of the lathe, drum, ring and other parts and the front and back face or milling surface, whether roughing or finishing process, the processing allowance of each surface is not directly cut to remove, need to cut two or more than two times. According to the size of the processing allowance, the number of times each surface needs to be cut. The processing allowance of each surface of the processing procedure is similar, and the number of times of cutting is basically the same. The processing allowance of each surface of the processing procedure may differ greatly, and the cutting times of each surface will be different. Before processing according to the different surface need to be confirmed the allowance of each surface need to cutting the number of times and each time the margin size of cutting removal, from outside to inside to remove one by one when machining allowance, on the surface of the machining according to this method, can make the parts of the residual internal stress, uniform step by step, can reduce the machining deformation of parts.
