Low-Cost, PC-Based Networked CAD/CAM/DNC System
A PC-based CAD/CAM/DNC system is used extensively in a university's Machine Tool Technology facility. The system supports CAD development, CNC program generation, and two-way file transfer among PC-compatible computers and multiple CNC controllers. From its modest beginnings, the system has evolved into a simple but robust DNC environment supporting all phases of manual and computer-assisted CNC program development. This case study describes system evolution, hardware and software requirements, the benefits of DNC on CNC operations and overall production, and also includes lessons learned from the experience.
