Intelligent Numerical Control of Profile Grinding

Abstract

The use of a single computer-aided control to automate production and its preparation creates a common technical base when the adjustable online model of the profile gear grinding operation allows compensating for the lack of online sensors built into the gear grinding system. In this case, the automation of design and production within a single integrated CAD/CAM/CAE system appears to be a single technological process in which not only general but also phased results are defined. This becomes possible by optimizing the entire (and not only partial) sequence of work performed. The introduction of negative feedback from the built-in online sensors of technological information (when such sensors are available) allows, based on monitoring the grinding system state and output parameters, to correct the setting of the CAE-system which is used not only offline but also in the online mode of CNC machine work. When the adjustment of the CAE system is regulated by deviation, this approach to control makes it possible to increase the efficiency of automated grinding systems. The paper provides a fundamental solution to the problem of making adjustments to the control program of a CNC machine based on the results of measuring the state and output parameters of the grinding system. Given as an example, a step-by-step sequence of actions to determine the parameters of grinding of complex-shaped machine parts (for example, gear wheels) makes it possible to understand the algorithm of operation of an intelligent self-training grinding system.
