Emulation of multi-axis numerically controlled machine tools

The MULTAX-PLOT program provides a method for verification of numerical control part programs. Combined with other tools, such as postprocessor listings and center line (CI) pen plots generated from the CI data files, the interactive MULTAX-PLOT program provides the machinist, the parts programmer and the postprocessor implementor a tool to visualize and troubleshoot machining commands. The MULTAX-PLOT program fills a significant void in the numerically controlled (NC) machining process. The center line pen plots are made from the CI data by one postprocessor, whereas the machine command file is generated by a different postprocessor. These two postprocessors may not produce identical results. However, the MULTAX-PLOT program displays the data from the machine tool's command file that will actually drive the machine tool. The principle benefits of the MULTAX-PLOT program are: a reduction in verification times by the system programmers, the NC parts programmers and the machinists; An early error detection method that reduces possible machine tool damage and scrapped parts; and improved machine tool utilization.
