Abstract: Goal of this paper highlight characteristics and spectrum of machining cutting sequences that programming system SolidCAM support. The practical goal of this paper is defining post-processor and machine simulation for 3-axis CNC machine like a tool for verification modern tool-path and generation G-code that will be used for cutting real part.

Abstract: According to needs of aspheric lens grinding and measurement with X/Y/Z 3-axis grinding machines, a CAM system is designed and implemented. The system, based on the parallel grinding geometry model, has realized the function of grinding locus planning, form error compensation, NC program auto-generation, on-machine measurement, grinding wheel on-machine measurement, simulation and technical database. To verify the stability of this CAM system, experiments were performed with three independent machining experiments. The experimental results indicate that the system realized the whole process of aspheric grinding, and it improved the machining efficiency and automation. Especially, this system adopted on-machine form error compensation technology and improved the machining accuracy. By implementing the error compensation integrated in the CAM system, the surface form error of a 430mm×430mm aspheric lens is decreased from PV8.2µm to PV4.1µm. The grinding accuracy was improved 100%.

Abstract: The CAM operation which generates a process plan and NC-data for mold machining plays an important role in mold manufacturing because it quite affects down stream processes such as NC machining, polishing, and assembly operation. This study proposes a supporting system which facilitates non-experts to perform the CAM operation easily and to select the high-quality NC-data which can increase machining productivity. It also designs and implements the support system in accordance with a CAM operation scenario. To check the usability of the support system developed, this study applies it to some practical examples of molding dies.
