Development Of Abrasive Wheel Numerical Controlling Dressing System Facing Grinding Machine Remanufacture Upgrade

In recent years,due to possessing following some excellences: simple machine tool configuration and forming movement, vile machining cost,high precision and expediently grinding some special gear (such as internal gear,gear wheel and so on) and other complicated profile, forming grinding is being attended by more and more people. During the grinding work, abrasive wheel's abrasive wear status is one of main factors which effect grinding quality.In the process of grinding with abrasive wheel, abrasive wheel will gradually lose the ability of cutting as the grains passivate. If abrasive wheel continues to be used to grind workpiece, the friction between abrasive wheel and workpiece will be increased and then bring about calorification, thereout, grinding quality will descend evidently. All these are caused mainly by grain being passivated, abrasive wheel surface being plugged up and abrasive wheel outline being distorted. Therefore, to dress the weared abrasive wheel in time and improve dressing quality and efficiency effectively will play an important role in ensuring grinding quality.This paper remanufactures the ordinary tool grinder at a loose end with numerical controlling technology by developing two coordinate abrasive wheel numerical controlling dressing system in the face of ordinary tool grinder on the basis of the idea of numerical controlling remanufacture. Numerical controlling remanufacture can not only resove the dressing quality and efficiency problem, but also make investment cost less, make efficiency more efficacious and bring the increment of enterprise intrinsic assets. This paper's idiographic research contents are as follows:Firstly, investigate complicated abrasive wheel section form numerical controlling dressing system which is an open system with the characteristics such as X-Y two axes linkage, performing MPC2810 movement progremme and standard G code, harf-closed cycle control and so on.Secondly, design the hardware configuration of numerical controlling system for abrasive wheel finisher and investigate beeline approach model and circular arc smooth model aim at forming abrasive wheel involute section form or other complicated axial section. In addition, we also investigate the offset problem on ball lead screw's screw pitch error and reverse gap.Thirdly, Dissertate how to realize the automatic layout of abrasive wheel section form dressing trace and the automatic creation of NC machining programme by means of the secondary development aim at AutoCAD. Develop CNC man-machine interactioin application software in advanced language Visual C++ 6.0. Implement machining process simulation. Design abrasive wheel finisher control panel Besides, translate standard injunction code into MPC2810 control instruction for resolving NC code's versatility problem.Finally, investigate and fulfil the integration of CAD, CAM and CNC and debug this abrasive wheel numerical controlling dressing system in the face of grinder remanufactural upgrade.Tryout effect proves that this developed numerical controlling dressing system facing complicated section form abrasive wheel on the basis of PC mode possesses a good many characteristics such as sample operation, good opening and high machining precisioin and so on. Therefore, this system has comparative great populization and application value.
