Development of CAM System for High Speed Milling

Abstract

The authors have developed a CAM system for high speed milling. The features of this CAM system are described in the following. An optimum zigzag path for high sped milling was adopted. Paths which prevent large tool load in the groove cutting for long cutting length are generated. At the tool approach area, the slant-cutting method was adopted, and at the same time, the feed speed was decreased. This contributed to the reduction of tool load and prevented chipping of cutting edge. A comparison of cutting results by the CAM developed and a commercially available CAM showed that the CAM developed realizes shorter cutting time, the same tool life and accuracy as the commercially available CAM. These results confirm that the CAM developed is useful for high speed milling.
