Improved Design Of Control System Of NC Lathe Based On 802C SIEMENS

Progress in science and technology,social productivity is also in constant development,advanced manufacturing technology is a rapid development of numerical control technology as the foundation,and gradually replace the traditional mechanical manufacturing technology,which is the development trend of mechanical manufacturing technology.CNC machine tools are widely used in manufacturing,then society is becoming more and more able to master the operation of CNC machine tools,programming and maintenance of the demand for the expansion of the application of personnel.In recent years,the major colleges and universities to set up the numerical control,and constantly reflect the social needs from the field of education.Then,with the development of education,especially the development of occupation education,school requirements of CNC machine tool training experimental platform is also more and more high,then based on the improved design of SIEMENS CNC lathe 802 C control system is particularly important.This design is made some improvements in SIEMENS’s SINUMERIK 802 C based control system design of CNC lathe,CNC lathe control system to make the control more functions on the basis of the original,the training of students also have greater flexibility and maneuverability.To carry out the design of the first to understand and grasp the structure,working principle and control method of SIEMENS 802 C CNC system and other knowledge,then according to the spindle control system,equipped with the knowledge and the existing equipment servo system,feed movement and other auxiliary motion control system in the library,the hardware of the CNC lathe for a comprehensive understanding,and the working principle of each module in the system in-depth understanding of,and the hardware circuit of the external,finally improved and designed to complete feed spindle control,motion control,motion control and other auxiliary functions.Through access to information,to master the 802 C SIEMENS CNC system built-in PLC features,the automatic turret PLC control program to improve the design.In addition,some data and main parameters of the numerical control system are set up,and the design of the automatic tool changing system is also increased.
