Advances in laser assisted machining of hard and brittle materials

Journal of Manufacturing Processes, 2020
Abstract Hard and brittle materials (HBMs) are promising materials for aerospace and astronomy applications, due to their excellent mechanical, optical, and chemical properties. However, they are difficult and costly to machine using conventional machining methods such as single point diamond turning.

Machining of hard and brittle materials: A comprehensive review

Materials Today: Proceedings, 2022
Abstract Modern machining trends are continuously expanding nowadays, especially the various vibrational-based machining processes (VBM) exemplify as ultrasonic machining, ultrasonic vibration assistant machining, and rotary ultrasonic machining (RUM) processes. Therefore, this review study has been focused on these three machining techniques with an

Hybrid machining of hard and brittle materials

Journal of Mechanical Working Technology, 1988
Abstract Combination of two machining processes may result in the increase of the productivity. This is an approach worthy to be tried especially for the machining of so-called difficult-to-machine materials. In this study, ultrasonic machining is combined with electric discharge machining.

Effect of erodent hardness on erosion of brittle materials

Wear, 1988
Abstract Data in the literature suggest that the relative hardness values of the erodent particles and the target sample may play a significant role in the erosion behavior of ceramics. This effect was investigated systematically. When the ratio of the target hardness to the hardness of the erodent particle approaches unity, there is a sharp ...

Use of ELID-grinding on brittle-hard materials

International Journal of Mechatronics and Manufacturing Systems, 2011
Electrolytic in-process dressing (ELID) is a grinding technology which enables to manufacture surfaces in a quality that is close to polished on advanced, brittle-hard materials such as used in optics. ELID grinding requires exactly aligned machining parameters of the grinding process.

Removal Mechanism in Wire-Sawing of Hard-Brittle Material

Materials Science Forum, 2004
A better understanding of the hard-brittle material removal mechanism in wire-sawing provides a basis for optimizing the wire-saw and processing parameters. The maximum cutting depth of each diamond grain in wire-sawing is given. It is proved theoretically that the deformation mode on the machined hard-brittle material surface gradually shifts from ...

Versatile facility for shaping hard and brittle materials

Review of Scientific Instruments, 1982
A simple-to-construct attachment for a conventional wafering machine is described. The attachment incorporates an ultra-high-speed air turbine with a diamond needle cutting tool, and turns the wafering machine into a versatile milling machine for hard and brittle materials.
