Measurement

Measuring and gaging are two distinct forms of dimensional inspection. Measuring is a direct-reading process, in which the instrument incorporates a continuous scale of units, against which the part is compared directly. Examples of measuring instruments include steel rules, Vernier calipers and micrometers.

An interview with Nikon's Corporate Vice President Tadashi Nakayama provides insight into the strategy of the firm's Industrial Metrology Business Unit, of which he is deputy general manager. In particular, he explained the company’s strategic focus on Quality 4.0, where digital, automated and connected inspection enables complete process control from design through manufacture.

It is certainly not news that, more and more, dedicated gages are being placed at the point of manufacture. Tight-tolerance measurements that were once performed in a semiclean room by a trained inspection technician are now being done right next to the machine, often by the machinist. But just because shop floor gaging has become commonplace, doesn't mean that just any gage can be taken onto the shop floor. To assure good gage performance, there are a number of specifications and care issues which need to be addressed.

Mahr Inc. has partnered with the University of Rhode Island’s (URI) engineering department to offer students the opportunity to work on real-world engineering and manufacturing problems. As part of the URI capstone project, students in their senior year are selected to take part in a year-long capstone project focused on automation of submicron precision finishing of ring gages.

When seeking straightness, as well as parallelism, perpendicular end cuts and other important geometric dimensioning and tolerancing features, the goals at Metal Cutting Corp. are cost-effectiveness and high-quality, tight-tolerance parts. To that end, the company finds that using qualitative test methods for straightness and other features consistently helps keep production costs under control while delivering the results that customers need.
