Summary and Conclusions
An experimental method of simulating the conditions of router action using a CNC lathe to test the cutting tool performance in peripheral trimming of composite material was developed. Validity of the proposed method is demonstrated by conducting the wear test on carbide inserts. Flank wear was not uniform, and the cutting edge shows abrasive tracks, grooves, and nose rounding. Chipping and edge rounding was dominant in interrupted cutting due to repeated impacts. Less grooving is seen in the interrupted case than in the continuous case. No signs of thermal damage or catastrophic failure was visible on any of the carbides used in this investigation. Machined surface damage was apparent under both cutting modes to the naked eye within 10 seconds of cutting time and life of the carbide is found to be less than 10 seconds.
