Calculation of the Reference Areas Cutting Profiles Taps
To tap a mathematical model for determining the reference area elementary cutting profiles allowing for the kinematics of cutting and shaping the location of items on the cutting part of the tool. Resulting in an analytical form the variation of the reference area of the cutting profiles as a set of values of axial movement of the tool allows you to calculate the pressure on the contact surfaces of a threaded nut tap couple. Calculated scheme for determining the elementary bearing surfaces of the cutting profiles. The charts of change of the accumulated supporting area are as an example built as far as the threading-in of cutting part of marker for the different sizes of back off of back surface of tooth. The equations of the contact areas of the thread pairs allow for analysis of the structure and geometry of the cutting tool from the point of view of the possibility of stabilizing the value of a breakdown in the first turns of thread cutting.
