adaptive controlling of CNC machines shows the block diagram of the system where sensors are incorporated to provide feedback loop on all the factors considered to control the positional errors and the dimensional errors.
Fig. Block Diagram of Self Tuning Regulator (STR) In the block diagram, the design block represents an on-line solution to the design problem for a system with unknown parameters.
The Adaptive Control Software should be capable of optimising the milling process, that is enabling the milling machine to operate at the highest feed-rate without violating or overriding the maximum permissible values of the horizontal force and torque acting on the cutter. These
Adaptive control is a control technique that provides a set of techniques for automatic adjustment of the controllers in real-time in order to achieve or to maintain a desired level of performance of the control system, when the parameters of the plant model are unknown and/or change in time.

Jan 1, 2019 · Block diagram of an AC system that maintains the resultant cutting forces (Fp) at a desired level (Fr) is shown in Fig. 1. The input to the AC system is the desired peak resultant force (Fr). The AC system tries to maintain the actual peak force on …
Block diagram of a CNC machine with adaptive control.
The basic block diagram of the ACC system used to achieve a constant cutting force in the high precision turning process is shown in figure 11.
The adaptive control is basically a feedback system that treats the CNC as an internal unit (see Fig. I), and in whieh the machining variables auto matically adapt themselves to the actual conditions of the ma chining process. AC systems for machine tools can be classified into three categories [3, 4]: (1) adaptive control with optimization
This paper presents the adaptive cutting force control for CNC milling machines. The research scheme divided the mathematical models, consisted of two parts: model of the feed drive system. Then it’s designed to the adaptive cutting force controller using Lyapunov’s method. The dynamometer is used to sense the cutting force and feedback to

Figure 1: Block diagram of adaptive control system. Adaptation Mechanism: An adaptive control system's primary characteristic is its capacity for self-adjusting parameters. Usually, an adaptation mechanism that monitors the system's performance and modifies the controller parameters as required manages this.
Fuzzy Logic Control or even more advanced control tech- niques such as optimized PD control using genetic algorithms or adaptive control, are used to control CNC machines.
