Automated gauging process and improved quality control

Product used: LAL95 series linear actuator

Problem: Customer was experiencing problems with lasers, including inconsistency, lack of reliability and insufficient repeatability, and no gauge correlation to the offline manually operated master gauge. The parts were hand sorted with a manual gauge using a dial indicator.

Solution: SMAC automated the manual gauging process. A linear actuator with 0.1um resolution encoder replaced the dial indicator, which provided a very repeatable motion profile. The SMAC solution was 40% better than their best manual gauging repeatability and reproducibility study.
