Stuck tool detector and related method

摘要

There is provided an apparatus and method for detecting stuck tools in automated machining operations. When a machining operation on a workpiece is finished, the tools are retracted from the workpiece. Prior to moving the workpiece to another machining operation, a stuck tool detector is moved along a plane of separation between the machine head and the workpiece. If a stuck tool is present, the detector senses the stuck tool and sends an alarm signal of the stuck tool condition so that the operator or controlling microprocessor based system is alerted to the stuck tool. Appropriate actions or repairs can then be carried out.
