    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 the cutting force controller. The output signal of the controller is a feed rate volume of CNC controller to control the feed drive system during a milling process. For experimental, it's defined 3 different depths of cut(DOCs). The experimental results compared to that between the actual cutting force response and the target cutting force. As experiment result, it can control the cutting force smoothly, the tool life increased and acceptable practice.

    In this paper, control of the output voltage in 11-level inverter is presented. The inverter is controlled by using pulse width modulation (PWM) technique. A novel 11-inverter source fed induction motor drive with sinusoidal voltage and current waveform is proposed. Variable frequency inverters to high precision in order control the speed of induction motor. The current in the inverter source can be controlled as constant or vary the magnitude of inverter current reference. The propose is controlled speed and decreased total harmonic distortion (THD) of output in the inverter which it fed to induction motor with V/F control.
