摘要：
The effect of varying the workpiece diameter on the cutting tool effective clearance angle has been investigated. Theoretical analysis of the relationship between the workpiece diameter and the cutting tool clearance angle is presented. To simulate this relationship experimentally, the cutting tool working normal clearance angle was kept constant, while varying the workpiece diameter, cutting speed and feed-rate. Tool-life cutting tests of cast iron bars were performed under dry cutting conditions using carbide tipped cutting tools. The experimental results revealed the existence of an optimum tool-life relationship under the above cutting conditions, indicating that the effective clearance angle varies with the varying of the workpiece diameter.
