MODERN TRENDS OF CAM SYSTEM FOR MACHINING ON CNC MACHINES

Abstract

The analysis of modern progress trends of CAM systems is presented. It is presented that in update versions of CAM systems the methods of cutting process control are used with the purpose of its stabilization. A control is designed on the basis of apriority information and supposes the solution of stabilizing task due to implementation of complex motions on a trochoidal trajectory. The trajectory parameters are calculated based on the criterion of cutting angle stabilization, that, in principle, does not result in stabilizing of process on its main characteristics. Solution of stabilizing task is offered on force of cutting with a control on a serve, the law of change of which settles accounts automatically at the simulation of cutting process. A control on the basis of current information foresees creation of the systems of automatic with loop-control on the controlled parameter of cutting process. Software is created for authentication of process of cutting which can be utilized as a feed-back control channel. Control on a posteriori information it is expedient to apply for an increase accuracy of machining. The algorithm of such control, which utilizes information of measuring of surface of detail after a trial passage-way for the correction of trajectory on the last passage-way, is developed. Experience of creation systems of optimum control for lathe treatment is presented.
