Grinding is one of the most important processes in the manufacturing discipline. One of the key goals for successful grinding is controlling the heat transfer in order to ensure that the workpiece material does not undergo any metallurgical changes. However, this problem can also be considered as an opportunity, as controlling the amount of heat that is conducted in the workpiece material can result in its surface heat treatment. The grind-hardening process is thus a novel, non-conventional machining process that can be used for the simultaneous surface hardening and grinding of metallic components.
The grind-hardening process has a history of almost twenty years. Since its introduction, numerous studies have been presented focusing on a number of aspects of the process such as its modelling, the impact of process parameters, the grinding wheel importance, etc.
The objective of this special issue is to present innovations and breakthroughs that have recently been developed in grind hardening.
Suitable topics include, but are not limited to, the following:
- Theoretical and practical aspects of the grind-hardening process
- Computer modelling and optimisation
- Microstructural and grain size control
- Material properties
- Hardening/tempering/stress relieving
- Residual stresses
- Nondestructive testing
- Failure analysis
- Thermal processing development
- Process monitoring and quality assurance
- Grinding wheel designs
