Beyond the shop floor: It has taken a while for CMMs to settle in on the shop floor
Article Abstract:
Measuring and monitoring equipment has move from specialized use to the shop floor, and the coordinate measuring machine (CMM) has the highest profile. The first dedicated CMMs were introduced in the 1950s, and digital readout systems were later fitted. CNC CMMs were introduced in the 1970, incorporating computer support and software. The greatest developments have occurred over the past 10 years. CMM on the shop floor has meant that the transport route between machine tool and inspection is shorter, however problems such as vibration had to be addressed, as well as the material from which the machine was constructed.

A measure of uncertainty: Many companies rely on CMMs for the verification of their manufacturing processes, but are they sure their machines are sufficiently accurate?
Article Abstract:
Coordinate measuring machines (CMMs) are flexible devices that can measure most geometric forms and relationships between features. It is important to choose a machine with the appropriate level of accuracy for the application, and potential CMM buyers should first decide on an uncertainty budget EB. It is also important to ensure that a machine remains in specification, and they should be tested on delivery.

Article Abstract:
Professor John Drane, leader of the post graduate course in Industrial Design Engineering at the Royal College of Art, says that good designers must contribute to the quality of life by designing products that people want. He believes that ergonomics is one of the most important aspects of good design.
