Design of the electical control system to FA-NCFD-1 NC Teeth Plate Indexing Table Training Platform
Abstract: Various kind of automation production equipment have been widespread with the upgrading and restructuring of the manufacturing sector, the first of these is the CNC machine tools which can greatly reduce the production hours and improve the quality of products. As an increasing number of CNC machine tools, the demand for the talent who can operate the CNC machine and able to maintain the equipment increased continuously. In order to improve the efficiency and effect of the training to the technical talents, various kind of different NC training equipment that consist of a part of the CNC machine tool emerged. Those training equipment can make trainees understand the composition and the principle of CNC machine tools. The purpose of this paper is to design the electric control system that consist of a PLC controller instead of a NC contraller of an NC teeth plate indexing training table that can let the trainee form a basic understanding about the composition, the principle and the common fault of the indexing table consist with multi-axis CNC machine tools.
