Parameterized machining method of rack on numerical control planer type milling machine

Abstract

The invention discloses a parameterized machining method of a rack on a numerical control planer type milling machine. The method is characterized in that: power accessories perpendicular to and parallel to a main shaft are arranged on the numerical control planer type milling machine; a reference tool setting block is mounted on the table board of the milling machine; the coordinate parameters ofthe machine tool main shaft, the power accessories and the reference tool setting block and the compensation parameters of a tool are measured; and a machining numerical control subprogram of a single cylinder is compiled according to the measured parameters, a main program of the numerical control subprogram is called, the main program and the subprogram are operated, movement, tool setting, correction and error measurement are achieved; accurate correction is conducted; and on the basis of coordinate offset, accurate machining of the rack is completed. The method has the advantages of simple programming, safe operation, high universality, rapid correction, convenient tool setting, accurate correction and accurate machining, and can be suitable for five-surface machining of various hexahedron parts.

Description

technical field [0001] The invention relates to a processing method for a diesel engine frame, in particular to a parametric processing method for a frame on a numerical control gantry milling machine, belonging to the technical field of diesel engine processing. Background technique [0002] With the development of diesel engine parts processing technology towards high precision and high efficiency, the traditional frame processing technology is difficult to meet the requirements. see figure 1 , the frame is a super-large hexahedral workpiece, its structure is complex, large in size, easy to deform, and difficult to turn over and turn. , It is easy to make mistakes. In the process of machining, calibration on the car, tool setting, compensation, coordinate setting, trial cutting compensation, benchmark correction, etc. are not only cumbersome and difficult to operate, but also require operators to climb heights, and there are certain safety risks.
