Abstract

Taking the middle plate as an example

the main difficulties in the machining of thin-wall plate-like die casting parts were described

and the machining scheme during development was analyzed to find out the control points to ensure the machining precision of the thin-wall plate-like parts

and to improve the quality of the process development.During the trial production

through data analysis

it is found that the thermal deformation of CNC machine results in insufficient process capability of machining holes.The error compensation method was adopted to solve the problems

so that the rejected parts with poor position accuracy were eliminated.
