Research On Control System Of Indexing Table Based On FANUC Auxiliary Function And PMC

Auxiliary Function and PMC Function are the key functions to realize digital control.Therefore,FANUC CNC has high quality,high stability and full function,and it occupies higher share in China's low-end CNC machine tool market.There is higher application value and practical demand,and it is in line with the "China intelligent 2025" national strategy that the manufacturing process needs to be innovated,and NC equipment needs to be upgraded in the enterprise,combining the development status and market conditions of CNC machine tools and accessories in domestic and foreign,and carrying out research on control system of indexing table based on FANUC Auxiliary Function and PMC Function.This paper studies the control system of indexing table based on FANUC Auxiliary Function and PMC,combining the actual needs of mechanical manufacturing enterprises,and the method of combining theoretical research with experimental verification is adopted.It was reviewed in the numerical control technology development and the status of the machine tool numerical control transformation,on the basis of detailed elaborated the increase of XH714 E machining center machine tool rotary indexing table of numerical control transformation plan,put forward using FANUC PMC and auxiliary function of the system to a new method of digital control rotary indexing table,extends the original three-axis linkage CNC machine process ability,improves the machining accuracy and production efficiency.The work did in this thesis including: 1.Relevant literature was consulted,and the research contents and achievements in the literature were reviewed.2.Four control schemes was discussed,that includes the control principles,hardware connections and comparative analysis of advantages and disadvantages,and confirm the choice of PMC control scheme.3.It were introduced that the structure,principle and type of the NC indexing table,and the initial load was checked and analyzed based on the finite element analysis.4.It was described that control scheme of indexing table based on FANUC PMC Function,and PMC program was completed,and B codes are developed and used.5.The mechanical and electrical coupling and the rotary precision test of the dividing table are completed,and the actual machining test is carried out,which verifies that the transformation scheme is correct,after the transformation of the CNC machine tool is completed.
