Internal Grinding is an approach to produce desired outcome with greater surface finish in metal cutting process. Unfortunately, external machining parameters play a vital role in research areas with numerous investigations. Considering this, present work focuses on the machining parameters on internal grinding process with necessary coolant oil as has been experimentally observed in our resear...

In this study, three different vegetable-based cutting fluids developed from raw and refined sunflower oil and two commercial types (vegetable and mineral based cutting oils), were carried out to determine for thrust force and surface roughness during drilling of AISI 304 austenitic stainless steel with HSSE tool. The uses of vegetable cutting oils was investigated in reducing thrust force and ...

Single point diamond turning tests were carried out on a B270 type glass. Submicrometer cutting conditions were applied in order to generate ductile response during single point machining. The profile generated by the rapid removal of the tool tip from the machined surface, analyzed by atomic force microscopy, showed that the brittle-to-ductile transition occurs at a few tenths of micrometers. ...

The orthogonal metal cutting process for a controlled contact tool is simulated using a limit analysis theorem. The basic principles are stated in the form of a primal optimization problem with an objective function subjected to constraints of the equilibrium equation, its static boundary conditions and a constitutive inequality. An Eulerian reference co-ordinate is used to describe the steady ...

Advancement in machining technology of curved surfaces for various engineering applications is increasing. Various methodologies and computer tools have been developed by the manufacturers to improve efficiency of freeform surface machining. Selection of the right sets of cutter path strategies and appropriate cutting conditions is extremely important in ensuring high productivity rate, meeting...

We present a compliant end-effector that helps in cutting soft tissues and sensing the cutting forces. The design of the end-effector is such that it has an upper threshold on cutting forces to facilitate safe handling of tissue during automated cutting. This is shown with nonlinear finite element analysis and experimental results obtained by cutting inhomogeneous phantom tissue. The cutting fo...

Chatter vibration in micro-milling is critical for the breakage of cutting tools. Therefore, dynamic stability important and chatter should be avoided. This paper presents a comparative study between two models prediction chatter. The difference source forces. first model uses mathematical force while second direct measured Both are solved time domain same criteria applied. results showed that ...
