OPTION Path control for MarForm
MCPC (Mahr Continuous Path Control) is used for moving along a reference profile in space by simultaneous measurement with two axes.
Suitable for contour measurements and freeform/line form tasks with MarForm
Measuring speeds of up to 5 mm/s are achieved, 10 times faster than tracking
Path control MCPC
In modern manufacturing processes, sophisticated technologies are used to produce increasingly complex parts. A final inspection in the measuring room remains an essential element of the quality control process.
However, in order to identify defects as quickly as possible, a shopfloor inspection is vital. Measuring the parts during individual process steps and manufacturing steps enables stability to be monitored and the process to be checked at an early stage as soon as control limits are reached. In the past, this check was usually carried out with manual measuring tools, simple measuring devices and instruments; now, however, given the degree of complexity and more stringent accuracy requirements, complex metrology techniques are needed.
Form testers conventionally measure a workpiece by moving the measuring probe along a high-precision reference axis. Until now, contour measurements have been performed within the probe measuring range or by axis follow-up using the probe signal (known as tracking or auto follow).
This function only works at a slow speed of up to 0.5 mm/s, and cannot be used where there are profile interruptions (due to bores or grooves, for example).
The new path control function MCPC (Mahr Continuous Path Control) on the MMQ 400 2 is used for moving along a reference profile in space by simultaneous measurement with two axes. Measuring speeds of up to 5 mm/s are achieved, 10 times faster than with previous systems.
The measured data is continuously recorded as a 3D point cloud. This is the first time that this type of coordinate measurement has ever been used in a form tester.
