Cutting force calculations for milling
 Prášil, Vojtěch ; Polzer, Aleš (referee) ; Klíč, Daniel (advisor)
Milling is nowadays one of the most important machining operations, and therefore it is necessary to deal with the processes involved. The main objective of this work is to compare different methods of calculating cutting forces with the results obtained by direct measurement. The experiment was carried out by direct measurement on a piezoelectric dynamometer where the workpiece was clamped while milling on a CNC milling machine. The first technique designed to determine the cutting forces analytically was their calculation on machining calculators. Two mobile application calculators and one online web application calculator were selected for this purpose. The second technique was to calculate the cutting forces using formulas from the standards. The cutting conditions corresponding to the dynamometer experiment were inserted into all calculations. The comparison shows that for face milling, the calculations from the standards and from the Hoffmann MC calculator achieved acceptable values compared to the measured ones. However, the results calculated for milling the sides differ significantly from those measured.
