Non-Contact Probe For On-Machine Metrology
ABSTRACT:
On-machine metrology is particularly important for diamond turning and grinding as it is difficult to remount and align a part if it does not meet off-line inspection criteria. There is also the issue of tool wear; a process that started well may fail part way through the cut, and if tool replacement is needed, it is vital to know that before removing the part. A means of rapid, non- contact, in situ profiling and roughness measurement could improve the productivity of diamond tool machining.
