An Apple microcomputer and a three axis milling machine are the basis for a CAD/CAM system with the capability of drilling and contour milling operations. The milling machine axes are driven by three stepper motors under the control of the Apple microcomputer and the ISAAC data acquisition module. An interactive part design program using high resolution color graphics has been developed. It employs lines, circles and points to define the geometry for the part. The design is entered at the CRT and stored as a CAM database on the user disc. Once the design is complete it is postprocessed and the milling machine and the Apple are connected through the ISAAC module. The raw part is set up on the mill and control of contouring is by the Apple microcomputer. The software has been designed to operate very similar to the EZCAM interactive part design software available on the Bridgeport CNC Mark II Series milling machine. It has been developed using Applesoft BASIC language and the 6502 Assembly language.
