Research Of The Control System Of Ultrasonic Magnetic Force Compound Grind Base On DNC

Develop continuously along with the molding tool, the molding tool type is more and more complicated,the accuracy and smooth of the molding tool surface requests raises continuously,such as the handicraft polishing ,ultrsonic polishing ,chemistry polishing and electricity chemistry polishing etc. those are existent problem to flow out continuously now in the molding tool type of the surface process.International and local scholar think it more and more important as the last processes of end a work preface .The ultrsonic magnetic force compound grind is reaserching abroad and use in finish machining tooling as one new finish machining process .At the same time, technics parameters and special requests to control system of the ultrsonic magnetic force compound grind restict severitily this technicla expansion .The magnetic force grinds mainly on three coordinateses ,by virtue of molding face data which three coordinateses scans ,finish by virtue of additional electrical engineering . this can hardly satisfy the ultrsonic magnetic force compound to grind request with the processes, mainly in following problems:(1) The equipments cost high,go against expansion in the business .Three coordinateses measure instrument cost higher, Be generally used for testing research phase, not fit to business enterprise great usage.(2)The equipments structure is complicated, disadvantage in common operation usage.The three coordinateses instrument belong to top grade equipment, to common operator in the workhouse can well-trained operation obviously not actual.(3)Can't revise on-line process parameter.The existing magnetic force grinds control system not involve the control of machining parameter ,even for add ultrasonics in ultrsonic magnetic force compound grind.(4)Didn't make general use existing technique and currency equipments.Finish maching on numerical control equipment is the usual working procedure before molding tool grind, Need to consider how to use numerical control code and existing NCMT sufficiently.The author is in a great deal of reading the reference domestic and international literature , combine with the topic of Ningbo City"theultrasonic magnetic force compound grind technique", studied project of the ultrasonic magnetic force compound to grind control system, advanced on foundation of make the best the existing number control of the equipments, make use of the DNC technique network and outside equipment (SCM ), reach the ultrasonic magnetic force compound to grind's control requests, carrying out to process parameter's view select , process process automatically control and modify the machining parameter on-line, satisfy ultrasonic magnetic force compound to grind to the comprehensive request to the controls system.This text mainly include following researches:(1)Introduced the principle of the ultrasonic magnetic force compound to grind and the technic parameter can influence process result,bring forward utilize existence NCMT and DNC after analysis the control system realize grind conceit , and analyzed DNC technical related knowledge further.(2)Combine the concrete topic give ultrasonic magnetic force compound grind's control system a total project, mainly analyzed control system of hardware/software system's composing,chose the hardware system and total frame of software system.(3)Introduced the related knowledge about serial communication,emphases analyzed of the hardware system to connect a single slice of a people's agreement and system the structure design of the machine part, studying the realization of the system net function.(4)Argument the possibility that the software system moderates the hardware system work, give the concrete design project and the key source code of the system control software, at last , carried on a humanized design to the movement interface of the software.(5) For example, the No.45 steel entity work piece the flat surface grind, introduction originally text research control system of experiment project, and carried on analysis the test results .The ultrasonic magnetic force compound of this thesis research grind the control system, have aggressive meaning to currently magnetic force compound grind technical expansion , also provide definite reference for the intelligenze alteration of the location NC.
