Finite element analysis based techniques are available to simulate cutting processes and offer several advantages including prediction of tool forces, distribution of stresses and temperatures, estimation of tool wear and residual stresses on machined surfaces, optimization of cutting tool geometry and cutting conditions. However, work material flow stress and friction characteristics at cuttin...
Abstract The aim of the paper is to present actual state techniques regarding influence cryogenic cooling in turning and milling process. Processing some materials impossible without tool or processed material. Hard-to-cut are increasingly used industry, so new methods these had be researched. Cryogenic most efficient method cool down turning, cutting tools. There a lot that not affected by low...
Needle biopsy is a common medical procedure where a needle is guided into the body and used to cut and remove tissue for evaluation. The geometry of needle tip and speed of insertion are important to the efficiency of tissue cutting. This study investigates the mathematical model on the needle tip cutting edge, which is divided into several elementary cutting tools (ECT). The cutting edge is mo...
