AI Technical Summary

Technical Problem

Traditional casting product polishing equipment has low programming efficiency for complex structures. Too much trajectory data exported by CAM software leads to time-consuming reading and modification. The trajectory generated by the model is different from the actual equipment operating trajectory, and there are safety risks and quality inconsistencies in manual operations.

Method used

The offline programming method of all six-axis CNC rough machining and grinding equipment is adopted to interactively set the workpiece and tool coordinate system, and the trajectory data is simplified by using the fitting algorithm to realize the overall offset and attitude adjustment of the trajectory data, simulate operation and collision detection, generate NC programs that meet the standards, and monitor the equipment status in real time.

Benefits of technology

It improves the polishing and programming efficiency of complex structural products, reduces data points, shortens the debugging time of new products, avoids safety hazards of manual operation, and ensures consistency of processing quality.

Abstract

An offline programming method for a full-six-axis CNC rough machining and polishing device. The method comprises: importing a three-dimensional model of a product into CAM software, interactively setting information of a workpiece coordinate system and a tool coordinate system of the three-dimensional model, selecting a route on which an operation is required, and generating path data; importing the three-dimensional model and the path data into offline programming software, and performing simplification processing on the path data; implementing an overall offset function, a single-point offset function and posture adjustment of the path data in the tool coordinate system; implementing simulation running of a tool and collision detection; on the basis of the path data and tool data, generating an NC program conforming to a program standard; and a six-axis device creating the workpiece coordinate system on the product; and monitoring a running state. Therefore, problems such as the polishing programming efficiency of products of complex structures being low, the follow-up reading, modifying and positioning being time-consuming due to the fact that CAM software exports excessive path data, and there being a certain difference between a model generation path and an actual device running path are solved.
