MANUFACTURING NON-CIRCULAR PARTS USING PROGRAMMABLE MULTIPLE-AXIS CONTROLLER

摘要

＜正＞Successful attempt is made to solve the problem of manufacturing non-circular parts with the aid of programmable multiple-axis controller（PMAC） integrated with high-speed electrical spindle. Principles of PMAC are introduced, and an NC-grinder system is integrated based on PMAC with proper software included. Control method and integration principle are discussed. Using PMAC’s online measuring and time-based controlling, high-speed and high-precision manufacture of non-circular parts is accomplished, yielding satisfactory result, which sets an important foundation for development of high-speed and high-precision NC grinder aiming at machining of non-circular parts.
