Case Study – Oaks Precision Fabricating, Inc.
90% Reduction in inspection time increases on-time delivery to customers

Oaks Precision Fabricating, Inc. makes parts for OEMs in the computer, medical and oilfield equipment industries. Because of this, they are required to inspect 10 per cent of each run and provide documentation on the inspection. Currently, parts are inspected either by a CMM or by hand, using calipers to check each and every hole. Due to the time involved, Oaks’ on-time delivery rate was approximately 83%.

Oaks were involved in the beta release of the LaserQC. Over the course of almost eight months, technicians from Oaks worked closely with Virtek engineers to refine the system. During that time, the speed of the system was evident to Oaks and once the system was operating at full capacity, Oaks kept the LaserQC, and made it the primary source of inspection.

Measurements that previously took minutes are now being completed in seconds, which translates into a ten minute savings per part. When dealing with runs of up to 10,000 parts and requirements of inspecting 10 per cent, these savings add up quickly. Initially concerned that the inspectors would have idle time, Richard Kaase, vice president, is no longer worried. “Because our punch operators have less downtime on first art inspections, our inspectors are busier because we are finishing more parts and getting them to inspection quicker. It’s had a different effect altogether than we anticipated,” Kaase recalled.

Since the LaserQC was introduced into the first part inspection process, the quality control bottleneck has been virtually eliminated. “We’re not going to let a part go out the door unless we inspect it. If delivery wound up running a day behind, or two days behind because the inspectors were getting backed up measuring everything and writing inspection reports, the parts would be late,” Kaase explained. “Now, they’re getting there on time more often. We’ve gone from 83% to almost 95%.”
