The Investigation of Precision Tapping

I. V. Ivanina

Abstract


The analytically derived the law of change of pressure on the contact surfaces of a threaded nut tap pair as a set of values of axial movement of the tool that allows you to analyze the structure and geometry of the cutting part of the terms of the possibility of stabilizing the value of a breakdown in the first turns of thread cutting. By calculation for taps installed the critical values of specific strength, which starts at the infeed support of subsidiary blade removal tool and more chips. which leads to a breakdown of the profile of thread cutting. Calculated scheme for determining the reference cutting edge elementary profiles. Gras-obtained feke pressure changes on the support edges of the profile  output taps for different values of the entering angle.
