Device Independent Program for Generating Machine Control Tapes

Shown is a flowchart for generating machine control tapes for a plurality of differing numeric control machine tools. Area 10 on the flowchart represents an integrated post processor program, and it gives the shown program its device independence.

Normally, a machine-control tape is generated by a part program 11, a general processor 12, and a post processor. The part program is a list of machine cuts to be made on the part to be manufactured.

The general processor 12 takes this information and converts it into a cutter motion file. The post processor then converts the cutter motion file into the machine control tape. Each post processor has been specifically written for the machine tool that will use the type generated by the post processor.

The integrated post processor 10 enables the adaptation of a generalized post processor program to generate a machine control tape for any numeric machine tool. This is accomplished by writing a general post processor program having variable program parameters which are adaptable to the particular machine tool to be numerically controlled. In addition, a unique machine tool module program is written to cover the few steps in the post processor program which are unique to the particular machine tool to be used. Such steps are so unique that they do not lend themselves to incorporation into a general post processor program. In this way, the integrated post processor program is independent of the machine tool it is generating a tape for, and adapts to each machine tool simply by calling out the appropriate parameters and the appropriate machine tool module program.

In operation, part program 11 is a list of the machine cuts to be made on a part to be manufactured. The general processor program 12 takes the input data provided by the part program and converts it into a cutter motion file. The cutter motion file is then processed by the integrated post processor program in area...
