igh-temperature corrosion/oxidation has been shown to be a major contributor to the wear of tungsten carbide when machining medium density fiberboard (MDF) (Stewart 1992). Consequently, a change in the properties of the tool material to resist wear from the adverse wood machining environment needs to be investigated. A deep cryogenic treatment shows promise as a tool material treatment for incr...

The purpose of the present investigation is to compare the statistically controlled machining solution of titanium alloys using ultrasonic machining (USM).

Relationships between the material removal rate, tool wear rate, surface roughness and other controllable machining ...

This paper describes the implementation of an integrated monitoring system for a CNC machine tool and its machining processes such as drilling, milling, turning and grinding. The monitoring system uses a variety of sensors such as force, torque, vibration, acoustic emission, and temperature to monitor the machining processes and the physical condition of the machine tool. The major aim is to im...

Optimization of process parameters is the key step in response surface methods to achieve high quality without cost inflation. The multi-response optimization of the machining parameters viz, chip-tool interface temperature, main cutting force and feed force on lathe turning of En-31 steel as alloy steel using RSM with grey relational analysis is reported. A grey relational grade obtained from ...

In this paper, a methodology for work material constitutive model based calculations of forces, stress and temperature distributions in orthogonal machining are introduced. Oblique moving band heat source theory is utilized and combined with modified Oxley’s parallel shear zone theory. Non-uniform heat intensity at the tool-chip interface is obtained from the predicted stress distributions util...

The lumber of Eucalyptus urophylla×E. camaldulensis was heat-treated at either 180, 190, 200, or 210 oC for 3 h. According to the national forestry standard methods for evaluating the machining properties of lumber, the machining properties (including planing, sanding, boring, mortising, shaping, and turning) of heat-treated and untreated control samples were investigated. The results indicated...

In dry machining, the tool-chip interface temperature is a critical factor affecting the engineering performance of WC–Co tools. As the temperature variation of the cutting tool in dry machining is similar to that in annealing process, the effect of tool-chip interface temperature on the mechanical properties of cutting tool materials in dry machining can be studied by means of annealing experi...

The use of titanium and its alloys has increased in various industries recently, because of their superior properties of these alloys. Titanium alloys are generally classified as difficult to machine materials because of their thermo-mechanical properties such as high strength-to-weight ratio and low thermal conductivity. Laser Assisted Machining (LAM) improves the machinability of high strengt...
