The bachelor thesis is focused on the adaptive control of technological parameters of the machining process. The work deals with the study of problems in the machining process, especially in CNC systems. In the first chapter of the bachelor thesis we analyze the concept of adaptive control, its reason in the machining process and classify the types of adaptive control in details. In the second chapter we deal with adaptive control systems that serves in the machining process to improve the quality of control and describe what types of adaptive controls we know. The third chapter is focused on the control circuits that keeps the quantity at the setted reading. There we describe what the direct and indirect regulations mean and also analyse the concepts of positional and speed control circuit. Next, we deal with action elements that are an integral part of regulatory circuits. We divide DC motors into several criteria. Then, we describe the asynchronous motors according to the principles and their speed control. Finally, the work deals with the sensors and analyzes them according to the type of measure, their position, speed, force and acceleration.
