Abstract


In recent years, with the development of the plastics industry , PVC and UPVC widely used , it is best suited for processing their cone twin screw extruder has also been a rapid development and wide application . The screw extruder is the heart, the improvement of the development of the extruder with the screw configuration and the corresponding development . Correct and screw machining the screw milling parameters design geometric precision direct impact on the quality of the extruder production capacity , performance, and extruded products . Conical twin-screw extruder is no exception. Led to the development of cone twin screw cone double- screw extruder , but there are still a lot of gaps in the theoretical studies of cone twin screw processing methods , very little research literature , far less than the breadth and depth of its research parallel twin screw can not be compared with a single screw . This topic focuses on CNC milling method study of cone twin screw straight major research profile toothed cone twin screw processing method , and to analyze the feasibility of using the flat end mills processed cone screw . Mathematical problems involved in the processing algorithm design and calculation , including the calculation and processing of the basic parameters of the cone screw cone screw cutter sites computing a series of mathematical calculations . Borland C Builder 5.0 programming software platform to implement these algorithms , and to reach the right result , developed out of the \This system can automatically generate the NC program , the CNC program incoming Shenyang Industry University Technology Development Co., Ltd. developed the spiral groove CNC milling , machining billets with a flat end mills , cone twin screw CNC milling . The success of the study of the subject , will reveal cone twin screw straight profile toothed CNC milling method , providing an important and valuable theoretical basis and experimental data . At the same time , we can promote the technological progress of the domestic cone twin screw machining , production practice has a certain significance , and lay a good theoretical basis for more complex toothed cone twin screw CNC milling work .
