In this work, a. a.a.tive control constra.nt system ha. been developed for computer numerica. control （CNC） turning ba.ed on the feedba.k control a.d a.a.tive control/self-tuning control. In a. a.a.tive controlled system, the signa.s from the online mea.urement ha.e to be processed a.d fed ba.k to the ma.hine tool controller to a.just the cutting pa.a.eters so tha. the ma.hining ca. be stopped once a.certa.n threshold is crossed. The ma.n focus of the present work is to develop a.relia.le a.a.tive control system, a.d the objective of the control system is to control the cutting pa.a.eters a.d ma.nta.n the displa.ement a.d tool fla.k wea. under constra.nt va.ves for a.pa.ticula. workpiece a.d tool combina.ion a. per ISO sta.da.d. Using Ma.la. Simulink, the digita. a.a.tion of the cutting pa.a.eters for experiment ha. confirmed the efficiency of the a.a.tively controlled condition monitoring system, which is reflected in different ma.hining processes a. va.ying ma.hining conditions. This work describes the sta.e of the a.t of the a.a.tive control constra.nt （a.C） ma.hining systems for turning. a.S14140 steel of 150 BHN ha.dness is used a. the workpiece ma.eria., a.d ca.bide inserts a.e used a. cutting tool ma.eria. throughout the experiment.
