Face plate of operation of numerical control of design of interface of numerical control operation should have an interface friendly, operation is convenient, mix by force from diagnostic function the craft characteristic that suits grinder. Round grinder has a movement to adjust inside rigid numerical control, grinding loop, emery wheel is single second nap loop, emery wheel for many times nap circulates and loop of nap of new emery wheel works 5 kinds in all means, after these working status always must be being started, ability is carried out, the each pace movement of the machine tool has certain chain requirement, it is only when these conditions are contented, this movement ability is carried out, operate a machine tool to make handlers convenient, a variety of directive information and necessary clew were designed on man-machine interface. The design of main control interface that touchs screen basically is offerred enter way of these 5 kinds of works or the operation entrance that enter parameter setting, diagnose ability oneself to increase, a certain number of operations or breakdown clew information were installed on the right side of the key-press on the interface that enters the mouth in the operation, but they just appear below the circumstance that accords with a condition, be in disappear latent state at ordinary times. In 4 kinds of of round inside nicety grinder automatic loops, "Grinding circulates " it is the most typical automatic loop. This design is an introduction circularly with grinding its control a function, the design train of thought with corresponding function of the others control and this is similar. Does grinding control a function circularly following: ? ? of  of Qiong of slander of  of greedy for food of ハ of  of ⒘ of  of ancient wine vessel of Shen  unoccupied place Di presses exterior loop begins to press button, does automatic loop begin: ?

Around afore-mentioned control the function asks, the design gives automatic grinding to control an interface circularly. Have a process circularly in grinding in, OK on feeling screen axis of status of process of monitoring loop condition, loop, action, X is current the position, feed and feed speed. When condition of not contented loop is started, wrong upper part of interface of control of automatic grinding annulus can hint " circular condition dissatisfaction is sufficient " ; and in undertaking circularly, the conference on the picture appears " interrupt circularly " by button, so that operate personnel,interrupt this loop at any time. 4.

At present this plan already carried out epilogue, finished the numerical control grinder with friendly interface to operate with indication picture, controlled the demand of treatment process action that accords with numerical control grinder logically, optimized the feed curve that craft of nap emery wheel asks, those who satisfied craft requirement is accurate affirmatory. Treatment precision accords with a requirement. Carry out a proof, this design is one kind can be developed continuously, the form of CNC system software that has innovation sex proposes development plan. After the project is carried out, to the control of numerical control machine tool plan added option, reduced numerical control machine tool to produce cost. The product of numerical control machine tool that uses this control program already sold as far as to and other places of Heilongjiang, Beijing, Zhejiang, user report result is favorable. CNC Milling
