The Probe Geometry strategy creates a probing operation to measure and verify critical features, such as holes, bosses, surfaces, walls, channels, and corners. The strategy supports two types of inspection method:
Probing cycles (macros), which are predefined routines on the CNC machine.
Probe paths, which are user-defined and enable the inspection of cylindrical and planar surfaces in various orientations not possible with probing cycles. They involve fitting geometric shapes, such as circles, cylinders, and planes to the features being inspected, a process known as geometric fitting.
Inspection results can be imported from a machine-generated results file or imported in real-time using a live connection between Fusion and the machine.
Example of a Probe Geometry operation for a circular boss using a probing cycle.
You can use the strategy to check features against specified tolerances to help catch any variations and perform actions based on the results. If measurements exceed the acceptable tolerances, the CNC machine can be instructed to stop with a message.
If using a probing cycle, the tool wear stored in the machine-tool controller can be updated to compensate for tool deflection and reduced diameter to improve the accuracy of future machining operations.
If using a probe path instead of a probing cycle, the strategy provides the ability to fit circles, cylinders, and planes to determine their circularity, cylindricity, and flatness. When fitting geometric features, you can set feature tolerances specific to the selected fitting type.
For circular fitting, you can set the following tolerances:
For cylindrical fitting, you can set the following tolerances:
For planar fitting, you can set the following tolerances:
