Variable gages are also indicated for three additional types of applications: where you can expect to optimize tool life and uptime by gaging the part and making corresponding machine adjustments; where scrap rates and loss of productivity are high; and where process variation is expected to be relatively high - measured by a CpK or CP of 1.
Finally, air-to-electronic gaging systems should be considered for applications where low initial investment is a requirement and flexibility is not.
An optical gaging system utilizes light to make dimensional, geometrical and positional checks on production parts.
Allison Engine Co, formerly Allison Gas Turbine Division, General Motors, saw that Kurt's modular gaging could provide other benefits as well.
Allison, a manufacturer of aircraft engines, had a new turbine blade program that required accurate fixture gaging to measure very complex geometries on a family of turbine blades.
In applications where there is interference between the part and the gaging contacts, the air/spring actuated linear bearing slide is used.
US automakers have always thought in terms of hard, dedicated gaging
You need gaging that is stable, reliable, and stays set once its calibrated.
With turning (particularly hard turning) challenging grinding, in-process gaging is moving into turning.
Both Control Gaging Inc, Ann Arbor, MI, and Marposs offer in-process gages for ID grinding-slim sensing mechanisms for inserting inside the grinder's workhead.
Many people doing statistics today are familiar with numbers but not with gaging.
Much of the gaging function is being transferred from inspection rooms and departments, out to machine stations on the factory floor.
LED and LCD displays are easy to read, and are quite easy to use by operators who do their own gaging, " says Funke.
Gaging systems range from the simple hand-held plug gage with air column or digital readout to more complex, fully automated systems with distributed processing of related activities such as machine monitoring, robotics, and information management.
Usually, measurement occurs after cutting stops and is better termed "post-process gaging.
