Part Inspection and Setup on Stone Working Machines
One of the issues in production environments, like environments with stone working machines, is represented by scrap parts due to wrong machining. A way to avoid this, is knowing how workpieces are fixed on the table (their real position with respect to the machine axes) and measure them after the machining. To obtain this kind of check, it is necessary for the machine to be equipped with part inspection systems, which are touch probes.
Part inspection identifies measurement operations that are carried out entirely inside the milling machine or machining center, in the very same conditions in which the cutting takes place.

Part inspection applications perform two check phases: work-piece set up and part inspection.
Before starting a process on stone, it is compulsory to know the exact position of the rough piece, its origins, and orientation. The lack of such information or its inaccuracy implies the risk of machining the part out of the required tolerances, due to misalignment. In other words, knowing the work-piece setup means significant scrap reduction.
Part inspection allows for a dimensional check right after machining. In this way, the user knows if:
- The part is correct and can proceed to the next process;
- The part has higher dimensions than requested, so it requires further machining;
- The part was badly machined; the immediate exclusion of a bad part prevents further process on it.
- Reduction of working and check times
- Increase of production efficiency
- Real-time determination of part position
- Scrap reduction
- Measurement of workpieces fixed on the machine
Marposs provides a complete range of part inspection applications to equip every stone working machine and measure parts of different shape.
- Optical transmission touch probes: probes ideal for machines of small and medium dimensions
- Radio transmission touch probes: probes for large machines, working on big parts
In addition, Marposs develops dedicated measurement software for every part inspection application.
