Abstract

In order to solve the problems such as low program compilation efficiency, more easiness for causing errors generated by manual operation, no easiness for quality control, high quality risk and the like, the invention provides a compilation method of a numerical control (NC) program for boring a high-precision symmetrical taper hole. The compilation method of the NC program for boring the high-precision symmetrical taper hole, provided by the invention, comprises the following steps of: establishing a bore hole machining coordinate system by taking an orifice circle center as the original point of the machining coordinate system; determining the main control plane and the control size of the compiled program; carrying out simple aided setting by utilizing conventional CAM (Computer-Aided Manufacturing) software; and automatically carrying out postprocessing to generate a required NC code. The compilation method has the advantages of convenience in use and capability of greatly increasing the efficiency for compiling the taper hole boring program and greatly improving the quality for compiling the taper hole boring program.

Description

technical field [0001] The invention relates to a numerical control machining control program preparation technology, in particular to a numerical control program preparation method for boring high-precision symmetrical taper holes. Background technique [0002] With the continuous improvement of product design requirements for structure and performance, more high-precision taper hole structures have appeared in product parts, and most of them are processed by CNC machine tools. Usually, a horizontal machining center or a boring and milling machine equipped with a U-axis is used to process this type of taper hole, and the computer-aided manufacturing CAM software of the commonly used CNC machine tool control program, such as: CATIA V5, NX or Hypermill, etc., does not provide the use of U-axis. It is a programming tool for shaft boring and tapered holes. Therefore, manual programming is often used to program boring taper holes. It is necessary to manually calculate the moving...
