Tool Compensation Control System Research

In the high-volume production machining, tool wear is an important factor affecting machining accuracy. In a micron in units of high-precision machining, this wear a greater impact. To solve this problem, which requires a can-micron as a unit, and can be simply and rapidly from the exterior of the tool to adjust the blade position compensation device. Only the right to conduct precision tool wear compensation in order to further improve the machining accuracy. Therefore, the precision machining tool in the process of compensation for machining process and equipment technology is an important research topic. This article describes several typical tool compensation device, its structure, principle, performance characteristics were analyzed. From a practical point of view of production, its positioning accuracy, reliability, and so conducted a comprehensive study. Through a comparative analysis of their advantages and disadvantages, ultimately chose the elastic deformation of micro-pressure feeding device, as a key tool compensation study. This is a high pressure hydraulic oil driven by elastic deformation produce small quantities of feed of the compensation device. This paper analyzes the elastic deformation of the micro-pressure feed device works, and carried out structural analysis and design. Discussed the composition of this program, tool compensation control system structure and basic functions, and to microcontroller core, made the tool compensation controller design. This paper introduces the hardware of the controller and the device is selected on the basis. Introduced the measurement signal input unit, the parameter storage unit, the data display unit, I / O interface unit, communication interface unit, proportional control output unit such as the design of hardware modules. And describes the system software design ideas and methods, while the main program flow is given a typical module subroutines. This article is compensated controller design tool provides a more complete solution.
