Evaluation of the behavior of cutting tools in the process of rolling, by using adimensional numbers

Abstract

The present paper consists of the application of the method of dimensional analysis using the Buckingham's p Theorem for the study of the tool wear of sintered high speed steel, conventional high speed steel, hard metal widia and tungsten carbide insert in turning. The testing in turning operations took place at workshops in Bogotá and Barrancabermeja, under different sequences of work piece materials and cutting conditions to wear out the tools. Data was collected to develop a graph relating two non-dimensional numbers (PI1 , PI2). Graphs constructed with collection of much data show to be convergent to a zone where all data can be agglutinated of dimensionless parameters PI1 and PI 2 that facilitate the comparisons between tools.The experimental comparison, based on the dimensionless parameters PI1 and PI2 demonstrated that it is possibleto elaboratea ColombianStandardto evaluate tools in several operational conditions.
