Sažetak
The paper presents cutting tools geometry analysis for the active part of straight fluted taps and a prediction model for tapping forces and torque. To derive the relation between the angles that define the geometry of the tools, the orientation matrices for taps coordinate systems are defined. Along with analytical model setup, the taps are additionally modelled in CAD package based on main parameters taken from the external database. The cutting coefficients for material combination for the workpiece (16MnCr5) and tool (HSS-E, EMo5Co5) were identified using the orthogonal cutting mechanics which is needed for prediction procedure. Proposed prediction model for tapping forces and torque of the machine tap, in addition to the effects of the major cutting edges, includes an action from minor cutting edges, too. Results of experimental verification for the proposed procedures and models are presented in this paper.
