Design And Implementation Of Disc Type Tool Magazine Control System

Automatic tool changing system of disc type tool magazine is a important features to realize the tool storage and switching. it can shorten the processing time effectively, improve the machining precision, and is suitable for flexible manufacture. A case study of the DETA2 type disc type tool magazine,design its disc type tool magazine change tool control system, based on the powerful logic processing ability of PMC. The main work is as follows:(1) The present situation of the development of domestic and international aspects of the disc type tool magazine is studied, and the structure of FANUC NC system is studied, and the PMC programming method is also studied.(2) Introduced in detail the structure and working principle of disc type tool magazine, Analyzing the basic knowledge of hardware circuit design in depth, the basic knowledge of programming.(3) According to the working principle of disc type tool magazine designed the pneumatic control circuit and electric control circuit. Electric circuit including main circuit, control circuit, PMC I/O interface and tool magazine writing diagram. In addition, all kinds of protection circuit design, anti-interference measures were taken.(4) Combining with the hardware circuit, based on the workflow design tool changer the tool magazine PMC control program, Including choosing tools program and cutting tool exchange of two parts. Choose tool program is the primary control of the cutting tool, considering the processing of various requirements in the edge of the sword; Tool exchange program USES is step by step program structure, the control process is clear. In addition, to guarantee the tool magazine work reliably, also designed the tool magazine protection.(5) From the perspective of application, the other details the control parameter and setting method of disc type tool magazine, tool magazine debug method, operation method of data table tool, in the NC machining program of the programming method of automatic tool change. By installing and commissioning the system to achieve the desired goal, to meet the actual requirements.
