Difficulty and Solution of Numerical Control Turning of Trapezoidal Thread
It was difficult to machine large pitch trapezoidal thread on the numerical control lathe,which mainly reflec-ted in the phenomenon of sticking the knife,the preparation of the program and the technical assurance of precision.Ac-cording to these difficulties of trapezoidal thread,through concrete examples,from the feeding method,the choice of the tool,the preparation of the macro program,the technical control of dimensional accuracy and other aspects,discussed turn-ing technology method of the large pitch trapezoidal thread in the numerical control lathe,thus solved the above problems,effectively ensured the quality of the processing,and improved the processing efficiency.The macro program was simple and practical,which could be used as a general template for large pitch trapezoidal thread or worm parts.
