New ways to increase production, reduce labor costs, and maximize floor space may be found by revisiting a 50-year old technology—rotary punching. Many part features and patterns can be punched and formed using pull-through rotary units at up to 300 feet per minute(FPM) in materials as thick as 1/16 inch. In addition, cam technology allows rotary punching and forming of material thicknesses up to 0.105 in. (12 gauge). Servo drives empower line speeds as fast as 650 (FPM).

Continuous improvement and statistical process control are useful, time-tested techniques—they have been used since the 1950s—but their use must be tailored to specific applications. For example, a typical manufacturing metric is parts per minute, but many roll formers should measure feet per minute. This and other tips can help roll formers accurately evaluate their productivity and measure the impact of process improvements.
