Heating Current Control in Electric Hot Minipore Drilling Hard-to-Cut Material
The key point for improving efficiency of Electric Hot Machining (EHM) is to keep an optimal heating temperature in cutting process. This paper introduces the principle and system for realizing optimal heating current control, Electric Hot Machining is applied to minipore drill of hard-material, a method of rapid determining the optimal heating current under various cutting conditions in electric hot drilling is proposed based on the conservation law of optimum cutting temperature. For a certain combination of tool and workpiece, the heating current in different cutting conditions can be obtained by changing heating current and measuring the cutting temperature in electric hot drilling.
