Research On Process And Control System Integration Of CNC Indexable Inserts Grinder

The rapid development of modern manufacturing technology, along with the requirements of the precision and efficiency of advanced manufacturing, has been promoting the fast advancement of metal cutting technology. As an advanced cutting tool in modern characteristics of the times, indexable cutters and indexable inserts play an important role in metal cutting. Because of its high durability, quick changed and low cost manufacturing, indexable cutting tool widely used in modern cutting process. Compared with other countries, current domestic indexable inserts periphery grinding machines are of less equipment type, backward technology, low grade and degree flexibility, which make it difficult to meet processing requirements. Facing with the situation of the high-grade grinding machines monopolized by foreign markets, the research group intended to make a research of the indexable inserts periphery grinding machines cooperated with Hanjiang Machine Tool Co., Ltd., which is supported by the key national projects.This paper focuses on " Research on process and control system integration of CNC Indexable Inserts Grinder ", for the purpose of achieving high accuracy, high efficiency, high automation, unmanned machining through depth research, including the following aspects:1. Based on the interaction of process and equipment, the secondary development of functional design and dedicated indexable inserts periphery grinding machines system was achieved on CNC8055and CNC8070, also the integration of grinding process and control system.2. With combination of machine tool structure and macro programming on CNC system, automatic control processes of2MK7130and2MZK7150were designed rationally, CNC8055and CNC8070macroinstruction was used to machine-control compiling, and automatic processing was done on machines.3. With combination of CNC system and on line measurement system, the online measurement of indexable insert mathematical model was established, the macro-programming of measurement was done to obtain results with high accuracy; a set of compensation method was designed for the real-time machine error compensation, which raised the production greatly.4. The diamond dresser principles was analyzed. The automatic wheel dressing method and control processes were completed considering the actual situation of machine. The life of the grinding wheels and the dressing wheels was monitored through CNC system for real-time.
