Innovative Computer-Aided Manufacturing

Computer Numerically Controlled (CNC) part programs generated by different CAD/CAM software packages are incompatible, which can lead to significant delay and increased engineering and programming labor cost if programs generated at one facility are used at another facility with a different CAD/CAM package. In the proposed research, software algorithms will be developed to convert controller-specific part programs (G-code) into a neutral format which can be edited by any CAD/CAM package. In Phase I, the technology will be demonstrated for a simple 3-axis milled part. An initial part program will be converted to a neutral CL format, edited using Pro-Manufacture, and post-processed to generate a modified part program, which will be verified by cutting sample parts on a machining center. The algorithms will be embedded in Third Wave Systems AdvantEdge™ Production Module tool path analysis program, so that the part program can be analyzed and modified to level forces and reduce cycle time as part of the conversion process.
