The single flat machine control equipment of numerieal control of machine tool designs
Abstract:The CNC systematic reference of this design in , the high grade system of numerical control in the interpolation method of soft, hardware combination. complete shrewd interpolation with hardware interpolation ware, carry out data point further dense melt , complete the processing of element out.This kind of method can reduce the requirement for computer sport speed , can raise substantially the running frequency that walks into generator. The step that this system can offer is controled into generator drive the limit frequency of pulse reaches 1 MHZs, can satisfy step very easily into generator drive to divide into control requirement carefully.
This systematic adopting CRT display uses the way of whole screen editor , make part program and the input of the parameter of machine tool to become very convenient, just in processing course can real time show the current state of machine tool completely, is convenient for operator for processing course keep watch on.
This systematic hardware adopts industrial standard( STD) bus line, little harden Gou. A shuttering has a kind of or two functions basically , realizes the function of shuttering level to scatter. Can expand according to the needs of user or as system cuts down , systematic composition is flexible.
This system is overall with a kind of function , and the practical C radius compensation algorithm of cutting tool realizes the C radius compensation function of cutting tool. Programming people need to draw up program according to element actual profile only, system realizes the center of cutting tool voluntarily along the law of element profile to deflection as well as element profile various corners, the conversion of form is transitional.
