Gabriel Hughes was once asked to calibrate a 2x4 at a previous job. While this may sound strange, the customer sent it in to have the precise dimensions calibrated. The wood was used to keep a door closed at a certain height, which they needed to monitor because of airflow.
In a lean manufacturing process, a poka-yoke method is employed to eliminate product defects by preventing, correcting, or drawing attention to human errors in real time. Industrial engineer Shigeo Shingo first applied the term poka-yoke (“mistake-proofing” in Japanese) to the Toyota Production System.
Historically, in-process gaging has not been widely used in the machine tool industry, but today that’s changing. Gaging companies have been evolving their products and making them easier to use, while enabling users to do more with gaging routines.
The height gage has transformed. From its infancy to today, the height gage has been in the grittiest shop environments. In spite of that, height gages also have the ability to meet the quality measurement demands of any precision laboratory. Regardless of how they are used or where, height gages have stood the test of time and remain an essential tool in every workshop.
Quality is often misunderstood. More specifically, the benefits of a well implemented quality management system (QMS) are not universally known and appreciated, and that can cost lives. Conversely, when executives and manufacturing personnel understand the benefits of a QMS, patient outcomes improve, the quality of life is enhanced, and manufacturers prosper.
Today’s manufacturing industry relies on the use of GD&T definitions, and the ability to verify parts directly to them for first article and production inspection and reporting. Only then do orders ship and the manufacturer gets paid. Price and scheduling are negotiable, quality is not!
