At present, some advanced CAD/CAPP/CAM systems have certain NC simulation functions, which are used to check the correctness of the cutting process of the tool, check the overcutting and interference phenomena, etc.
But directly control the method of machine tool simulation processing through NC code And not much software. In addition, if the simulation software can be directly embedded into the actual processing system, making it a supporting environment for actual processing, it will be of greater significance.
The main functions and key technologies of the system
Through the modeling of the processing environment, the system uses three-dimensional graphics to display the CNC machining process, and uses geometric models to check various problems in the process. The system mainly provides the following functions.
Modeling of CNC lathe bed, guide rail, tool holder, tool, tailstock, and workpiece; simulation of the movement of the machine tool and tool during processing and the simulation of the cutting process; collision and interference inspection between the tool and workpiece, chuck, tailstock, etc. , And has an error alarm function; simulation chip flying and sound effects. The machining process is required to be directly controlled by the NC code, and it supports manual modification of the NC code.
The key technologies that the system mainly researches and solves include geometric modeling, geometric definition for machine tool equipment and processed parts and their clamping methods, translation, interpretation and conversion of NC codes, geometric motion simulation and physical simulation of the processing process; processing process Various inspections (program inspections, various parameter inspections, collision inspections, etc.) etc.
