abstract

The machine tool probing can improve efficiency in many different ways, but it is underused in almost every manufacturing location. Part of the reason, probing is underused, is the complexity that often comes with adding probing to the process. Manufacturing companies generate milling and drilling tool paths with ease, using any of a variety of CAM systems. But probing calls for macros that are often either added to the NC code through manual editing, or else entered right at the CNC. This papers present a method to address this shortcoming. A method has been developed using a swept-volume computation to emulate the physical environment for probing process. The virtual probing trajectories are obtained from CAM software. In the mathematical algorithm, the swept volumes of the probing tools are computed from the probing tools’ geometric data and trajectories. Collision operations are then performed on the swept volumes of the virtual probing tools and the virtual machined workpiece to verify the probing process.
