You face special problems when working with cnc machining internal cavities. These spaces often take more time and money than outside features. Internal cavities need careful planning. Tool deflection and chip evacuation become big problems as you go deeper. The main problem here is the depth-to-width ratio. Making a deep, narrow pocket is one of the hardest parts of complex CNC machining. As a tool goes deeper into a cavity, many problems can happen. These problems can hurt the quality of the finished part. The biggest problem is tool deflection. A long, thin cutting tool can bend more easily when…
