Information : Tool Calibration Recall System
Lockheed Martin Electronics and Missiles (E&M) maintains a tool inventory of approximately 33,000 items, of which there are nearly 12,000 requiring some periodic calibration. To better ensure this process is completed on time and to ensure that no uncalibrated tools are on the shop floor, the company developed a highly effective and reliable computer monitoring system for tracking and recalling tools for recalibration. This system is critical to maintaining the requisite quality control for the precision shop work environment.
Since 1986, Lockheed Martin has linked the Property Control System (PCS) with the Standard Tool Inventory Control System. This link controls tool checkout to a user who is personally responsible for its location, and from whom the equipment is recalled for calibration.
Some self-calibration is performed on items in the field. Also, some metrology stations are collocated in the critical shop areas to reduce the time a tool is out of service for recalibration. The virtual real-time nature of the tracking and control system, combined with a barcoded user/tool log-in process, has improved quality in the manufacturing process (MP), and reduced the loss and abuse of tools in general.
