An overview on machinability of hard to cut materials using laser assisted machining

, 2021
Machining of hard to cut materials is a difficult task nowadays. High cutting powers, poor surface grade, less tool life are the major concerns related to machinability.

Hard Machining, Component Quality

2013
For the application of components under tribological, corrosive or dynamic operational loads, the properties of their surfaces and subsurface zones are of crucial relevance. These are the areas of the workpiece where property alterations will arise due to the impact of a manufacturing process.

Hard Machining, Process Design

2013
The cutting of hardened ferrous materials and hard coatings with hardnesses above 47 HRC is referred to as hard machining (more precisely: cutting with geometrically defined cutting edge).

Machining Characteristics of Hard Materials

CIRP Annals, 1988
Abstract The hardening of steel rather lowers the cutting forces in many cases. This is the result of high shear angle and the saw-toothed chip formation due to the poor ductility of hard materials. Reinforcement of Al alloy with fiber also decreases the cutting forces. However, the hard materials wear the cutting tool rapidly and increase the forces,

Modelling of hard part machining

Journal of Materials Processing Technology, 2002
Abstract The paper initially reviews the use of finite element modelling (FEM) to determine orthogonal machining performance. Over the last decade, the development and use of FEM to evaluate the effect of tool coatings, cutting environment and chip formation on cutting forces and temperatures, etc., has increased dramatically.

Machining of Hard Materials

2008
This chapter presents basic knowledge on the special kind of the machining process in which a workpiece material hardened to 45–70 HRC hardness or more is machined with mixed ceramic or CBN tools. An extended comparison with finish grinding, as well with other abrasive finishing processes, is carried out.
