Modeling and analysis of the cutting temperature of titanium alloys for quasi-intermittent vibration assisted swing cutting

Journal of Materials Research and Technology, 2023
EVC has proven to be an effective means of machining difficult-to-process materials. QVASC inherits EVC's intermittent cutting and friction reversal advantages, eliminating EVC cutting residues and improving machining quality.

Cleaved end-face quality of microstructured polymer optical fibres [PDF]

, 2006
The cutting of a microstructured polymer optical fibre to form an optical end-face is studied. The effect of the temperature and speed of the cutting blade on the end-face is qualitatively assessed and it is found that for fibres at temperatures in the ...

Comprehension of chip formation in laser assisted machining [PDF]

, 2011
Laser Assisted Machining (LAM) improves the machinability of materials by locally heating the workpiece just prior to cutting. Experimental investigations have confirmed that the cutting force can be decreased, by as much as 40%, for various materials ...

Effect of Coated Composite Micro–Texture Tool on Cutting Shape and Cutting Force during Aluminum Alloy Cutting

Machines, 2023
Aluminum alloy materials are very difficult to break in the processing process; chip accumulation leads to poor processing stability. In this paper, a coated composite micro–textured tool is presented.

In-Process Cutting Temperature Monitoring Method Based on Impedance Model of Dielectric Coating Layer at Tool-Chip Interface

Journal of Manufacturing and Materials Processing, 2022
This paper introduces a novel approach to in-process monitoring of the cutting temperature at the tool-chip interface (TCI). Currently, there are no tools available in the commercial market for measuring and monitoring cutting processes at the TCI region.

The Cutting Temperature

Transactions of the Japan Society of Mechanical Engineers, 1957
The cutting temperature is one of factors which exert a large influence upon tool-life. We measured the temperature distribution in the vicinity of tool-point by thermo-color method, using specially designed dividable orthogonal cutting tool, and the mean cutting temperature by thermo-couple method between tool and work.
