This paper presents a comparison of experimental results and a fuzzy rule based system model for calculating the cutting force in the turning operation. A full bridge dynamometer was used to measure the cutting forces over the mild steel work piece and Cemented Carbide Insert tool for different combinations of cutting velocity, feed rate and depth of cut. The rake angle, approach angle and nose radius of the cutting tool insert is kept constant throughout the experiment. This fuzzy model consists of 27 rules and Mamdani Max-min inference mechanism was used. The Taguchi designs of experiments were used to determine the number of experiments. Also, an attempt had been made to analyze the influence of the parameters using the regression analysis which yields a maximum error of 3.214% at the time of prediction which was smaller. The experiments are planned based on Taguchi's design and the measured cutting forces were compared with the predicted forces in order to validate the feasibility of the proposed design. The percentage contribution of each process parameter had been analyzed using Analysis of Variance (ANOVA). Experimental results were compared with the regression analysis and predicted fuzzy model. The difference between experimental and predicted results was obtained as around 98.84%.

Multi-component cutting force sensing systems in manufacturing processes applied to cutting tools are gradually becoming the most significant monitoring indicator. Their signals have been extensively applied to evaluate the machinability of workpiece materials, predict cutter breakage, estimate cutting tool wear, control machine tool chatter, determine stable machining parameters, and improve surface finish. Robust and effective sensing systems with capability of monitoring the cutting force in machine operations in real time are crucial for realizing the full potential of cutting capabilities of computer numerically controlled (CNC) tools. The main objective of this paper is to present a brief review of the existing achievements in the field of multi-component cutting force sensing systems in modern manufacturing.

Original scientific paper In this paper, the orthogonal cutting force model is proposed comprising forces due to flank wear in addition to the forces for chip formation during the hard turning of round bar made of steel 60WCrV7 hardened at 55+2HRc. Cutting force model includes two tool conditions: perfectly sharp tool with VBB = 0 and tool with maximum permissible flank wear VBBmax. Based on cutting force measurements and established force relationships between the wear forces and forces for chip formation, it is possible to analytically predict the friction coefficient between the tool and workpiece. From pure geometrical relationships between forces the equation for the friction angle between the tool flank and workpiece can be derived. The friction coefficient at the toolworkpiece interface was measured using block-on-the-disc tribometer. Predictions of the friction coefficient by means of established mathematical model are compared with experimental results, and overall a good agreement is observed. Keywords: cutting forces; flank wear; friction; hard turning Sile rezanja kod tvrdog tokarenja koje uključuju stražnji pojas trošenja i njegov utjecaj na trenje između alata i obratkaIzvorni znanstveni članak U ovom radu, predložen ortogonalni model sila rezanja obuhvaća sile nastale zbog trošenja stražnje površine pored sila za formiranje čestica pri tvrdom tokarenju okrugle šipke napravljene od čelika 60WCrV7 koja je otvrdnuta na 55+2 HRc. Model sila rezanja obuhvaća dva stanja alata: idealno oštar alat s VBB = 0 i alat s maksimalno dopuštenim pojasom istrošenja stražnje površine VBBmax. Na osnovu mjerenja sila rezanja i uspostavljenih odnosa između sila zbog trošenja stražnje površine alata i sila za odvajanje čestica, moguće je analitički predvidjeti faktor trenja između pojasa istrošenja stražnje površine alata i obratka. Iz geometrijskih odnosa između sila može se izvesti jednadžba kuta trenja alata i obratka. Faktor trenja između alata i obratka mjeren je pomoću tribometra blok-na-disku. Predviđanja faktora trenja pomoću uspostavljenog matematičkog modela uspoređena su s eksperimentalnim rezultatima i uočena su dobra poklapanja.
