Machine-integrated inspection systems can improve quality, profitability

Posted Leave a commentPosted in Equipment and Tooling, Quality and Metrology

Stopping a machine to measure a workpiece is a waste of time. Not only is a high-priced piece of CNC equipment being taken out of production, but the measurements obtained when a machinist leans into a machine with a micrometer or bore gage can’t compare in accuracy to those generated by a coordinate measuring machine […]

Looking for trouble: Is your coordinate measuring machine up to snuff?

Posted Leave a commentPosted in Equipment and Tooling, Quality and Metrology

Often abused and generally unappreciated, coordinate measuring machines (CMMs) are the underdog of the machining world. That’s because, unlike their metal-cutting cousins, CMMs don’t actually produce anything. No chips, no shiny machined parts, nothing but measurements and statistics. But remove the lowly CMM from any shop and you’ll be checking parts with height gauges and […]

Programming Quality – Knowledge is just as important as the program when measuring with an automated CMM

Clamp the part to the surface plate. Enter a few parameters. Grab the joystick and go. When checking a hole location, or measuring the distance between two machined surfaces, that’s about all you need to know in terms of coordinate measuring machine (CMM) operation. Unfortunately, most inspection procedures are more complex, and good metrology requires […]
