Automation of control and management of technological process

Abstract

The article describes the materials and methods used to automate the control and control of the technological process when processing parts on multi-purpose machines. The main control element is a measuring probe, which is integrated into the machine and allows measurements to be made at the processing workplace. This makes it possible not only to control the size deviations of the parts, but also to adjust the processing parameters in real time. The measurement process is performed in a preset machine program, where the coordinates of the characteristic points of the part are measured. Coordinate deviations are used to calculate the accuracy of processing. The measured deviations can be compensated by automatic correction in the control program. However, the accuracy of measurements on the machine is limited by the accuracy of its positioning, which is inferior to coordinate measuring machines. The positional coupling control system makes it possible to compensate for spatial deviations when moving machine components caused by equipment inaccuracies and other factors. To increase accuracy, software algorithms are used that allow you to adapt the processing parameters to the current deviations. In addition, algorithms have been implemented to automatically calculate deviations and make necessary adjustments to the control program of the machine. The use of microprocessor control allows you to quickly change the program commands and thereby maintain the continuity of the processing process with real-time adjustments. Thus, the proposed approach of automation of control and control allows to increase the accuracy of processing by integrating measuring and correcting systems into the control circuit of the machine.
