Propellers comprise fan-shaped structures with spiral blades. The real-time measurement of cutting and grinding forces during the milling and grinding of propellers is difficult to achieve. The spindle motor current is a common parameter used to measure cutting force. However, data related to this parameter are not accessible during the use of DC motors for cutting processes and can be obtained only from servo motor drive systems. Given these considerations, in this study, we adopted LabVIEW software to develop a program for use in combination with an inexpensive sensor to achieve the simultaneous measurement of the cutting force and motor current. The program was verified to accurately depict the relationship between the cutting force and the motor current of reconfigurable precision five-axis machine tools, rendering it a viable alternative to measurement schemes that rely on expensive force sensors. Subsequently, the developed program was further tested by measuring changes in spindle motor current while cutting three blades to produce a 3D-printed polylactic acid propeller.
