Special aspects of machining of internal threads by measure tool
Journal Title: Журнал інженерних наук - Year 2016, Vol 3, Issue 2
Abstract
Based on an analysis of recent studies of various machining methods the disadvantages of existing methods of internal threads machining have been identified. The proposed method of machining round threads by up to measure tool demonstrated superior performance in comparison with known machining methods. Further study of possible use of up to measure tool in machining other types of threads is an urgent task, the realization of which is necessary to determine of parameters of tool diameter and its motion trajectory. The real cross-section profiles of the thread were determined by graphical method. Analytical method derived mathematical expressions that bind the pitch and thread shape with the tool dimensions and machining equipment settings. The nominal diameters of up to measure tool radius and spiral trajectory of its motion for the metric, inch and a round thread was defined. The coefficients of regression, which characterize the degree of influence of the internal diameter and the thread pitch on up to measure tool diameter.
