Imaging interactive numerical control turning automatic programming method and system

Abstract

The invention provides an automatic graphical interaction-typed numerical control (NC) turning programming method and system used for improving programming efficiency and NC code quality, prompting quick product process realization (RPPR) and integrated product process development (IPPD). The technical proposal of the invention is that the automatic graphical interaction-typed numerical control turning programming method is characterized in that the method comprises the steps of: reading in blank and part drawing, removing redundant information, and judging whether the graphics are exact; leading the graphics to have real-time interaction function and be capable of correcting the information of the part processing surface, including processing surface type, exact geometrical information and surface roughness; determining whether to execute the corresponding system function modules by carrying out automatic programming or auxiliary programming or mixed programming according to the selection of the user. The automatic graphical interaction-typed numerical control turning control system is characterized in that the automatic graphical interaction-typed NC turning control system comprises a CAD data reading-in module which is respectively connected with an automatic programming module, an auxiliary programming module and a mixed programming module which are respectively connected with an automatic track layout module which is connected with an NC code generation module.

Description

technical field [0001] The invention relates to the field of numerical control turning control systems, in particular to a graphic interactive numerical control turning automatic programming method and system capable of flexibly formulating numerical control processing technology and cutting trajectory. Background technique [0002] The automatic programming of NC turning is built on two mature technical paths, that is, automatic programming tool APT and computer-aided design and manufacturing, that is, CAD / CAM technology. [0003] At present, the processing-oriented and small-scale programming systems with a certain scope of application developed on the basis of APT include ADATP for contour control and AUTOSPOT system for point control in the United States. Germany has developed EXAPT (Extended Automatically Programmed Tools)-1, EXAPT-2 and EXAPT-3 series of small automatic programming systems for point processing, turning processing and milling processing respectively, as...

AI Technical Summary

Problems solved by technology

Various small special-purpose CNC language programming systems derived from APT have the following three types of disadvantages when they are used for CNC turning or milling programming: (1) programmers need to learn and master the CNC language, (2) need to process parts information Converting into text or digital information is not only unintuitive, but also has a high error rate during the conversion process. (3) CNC language programming is currently still in the form of batch processing, that is, the part source program written in CNC language is only processed once after inputting into the computer , and manual intervention cannot be performed during the processing, so that the operation result of the instruction code cannot be modified

On the other hand, with the continuous advancement of CAD / CAM technology, my country has also conducted preliminary research and discussions on how to realize the automatic programming and simulation of NC machining procedures on the basis of introducing foreign advanced CAD / CAM technology, including graphical Development of NC lathe auxiliary / semi-automatic programming system, but whether it is a NC programming system developed abroad or domestically, for such things as cross-platform features, CAD graphic data optimization, NC machining technology and automatic planning of tool paths, and 3D machining process simulation based on virtual reality research is still at the level of theoretical analysis and methodology

For the fast-growing industrial cluster of domestic high-end CNC systems, there is no specific technology and software system implementation in the supporting technical fields such as graphical interactive, computer-aided or automatic process problem solving and process specification formulation in turning programming.
