Abstract

 Cutting force is an important parameter in turning because it reflects the interaction between the cutting tool and the workpiece. However, commercial cutting-force measurement systems can be expensive and may not be readily available in student laboratories. This study presents a low-cost cutting-force monitoring system developed using an Arduino Uno and a dynamometer, and evaluates its use during the turning of a mild-steel bar on a centre lathe. The cutting forces produced by grooved and un-grooved high-speed steel (HSS) tools were compared. The recorded mean force components for the un-grooved tool were Fx = 1.00 N, Fy = 40.25 N and Fz = 11.12 N; for the grooved tool, they were Fx = 1.00 N, Fy = 46.09 N and Fz = 10.74 N. Compared with the un-grooved tool, the grooved tool showed a 14.5% increase in Fy and a 3.4% decrease in Fz, while Fx remained unchanged. Since only overall values were available and trial-wise readings were not recorded in the results workbook, these findings are descriptive and should be interpreted with caution. The identical Fx values also require verification.
