Effect of Threaded Holes Parameters on the dynamics Shaping of the Standard Metric and Modified Threads

I.V. Ivanina

Abstract


A mathematical model for determining the status and parameters of cross-section layers of cutting elementary cutting profiles was developed, which are based on imitation of the intersection of the cone forming the cutting tap with the contours of the theoretical thread profile and marginal contours of the workpiece under thread. Installed in the ana-lytic relationship as the radial forces with structural and geo-metrical parameters of threaded pairs of tool-item allows you to specify recommended intervals of hole sizes for the thread to ensure a minimum value of the radial component of the cutting force and power characteristics count modified cutting threads. Developed engineering technique destination diameter threaded holes aimed at improving the accuracy and stability of the threading process.
