Abstract
The invention describes a method for the inspection of machining tools used in computational numerical control (CNC) machining centers. The invention will observe a machining tool immediately after use to determine if it has been damaged. The invention is based on a machine vision technology that uses one or more image sensors to acquire, locate and compare the tool to a good model. The inspection equipment is designed for implementation in the CNC automatic tool changing system and will alert the operator that tool has been damaged before the next operation. This immediate response of the invention will contain defect components and prevent damage to subsequent components. With the addition of an infrared image sensor the invention is capable of detecting worn or dull tools that may damage a component due to excessive heating.
