Read MoreNew Treatment Extends Tool Life
Heat is the major enemy of the cutting tool. Tool life is a measure of how long an individual edge can effectively hold up to the temperatures and pressures that are generated in the cutting zone.
Read MoreBetter Math Makes Scanning Stronger
Evaluating the suitability of a CMM for an application traditionally revolves around determining measurement uncertainty relative to the workpiece size and required tolerances. Generally the CMM should be 10 times more accurate than the tolerance it will verify. But what is the best method of acquiring the data?
Read MoreAll-Digital Upgrade Starts At The Low End
