Stamping Condition Monitoring : A complete measuring and process control system for Husqvarna Edge

Sammanfattning: The project covers the substitution of a stamping shut height measurement at the chainsaw chain factory Husqvarna Edge, with a new sensor-based processmonitoring system, set to increase productivity and decrease running costs. The workflow covers the span from external and needs analysis to development and testing of both hardware and software, in conjunction with communication with external suppliers to find the most usable and profitable solution going forward. Regarding hardware was inductive / eddy-current distance measurement sensors the most suitable for the stamping press environment, providing high sample rate and repeatability to a micrometre level, while subjected to oil andvibration. Husqvarna’s state of the art stamping setup is not yet fully supported by process monitoring suppliers, which resulted in the creation of the new program called Live Height, which was successfully used for sensor evaluation and serves as an example for suppliers to expand upon. This work provides several options in different price ranges for Husqvarna’s management to make decisions upon.
