G74 end drilling and grooving cycle; Z-37 hole bottom coordinates (the distance from the processing start point to the end point is the depth of the hole); I 18, each feed speed of Z axis, and each feed speed of K2 and Z axis; R0, r is the X-axis tool withdrawal (offset). If omitted or 0, only the Z direction will be retreated at a time; F 160 feed speed. Program running state: the tool cuts from coordinate 0 to-160MM position every minute. Back the cutter 2MM to -36 and 2MM to -37, and then quickly move to the cutting starting point, waiting for the next command! This instruction is mainly used for machining difficult-to-machine end faces, and the purpose of setting k is cutting.

Firstly, according to the requirements of drawings, the process route is determined according to the principle of processing first and then processing.

Select the cutter, align the cutter and determine the origin of the workpiece.

Determine the cutting parameters: machining excircle and end face, spindle speed 630rpm, feed speed 150mm/min. Cut off, the spindle speed is 365438 05 rpm, and the feed speed is 65438 050 mm/min.
