Surface Integrity in Hybrid Machining Processes

Nontraditional and Hybrid Machining Processes

Surface integrity predictions and optimisation of machining conditions in the turning of AISI H13 tool steel

Surface integrity (SI) plays a very important role in functional performance. It is dependent on a large number of machining parameters. The major concern of industry is to know which combination of machining parameters provides the best SI of machined components. Traditionally, surface roughness is considered to be the principal parameter to assess the SI of a machined part. However, residual ...

Process Mechanics and Surface Integrity Induced by Dry and Cryogenic Machining of AZ31B-O Magnesium Alloy

The corrosion resistance of magnesium alloys depends mainly on its surface integrity. Previous experimental studies have shown that machining can induces small (nano-scale) grain size, compressive residual stresses and basal plane crystallographic texture, which significantly improve the corrosion resistance of magnesium alloy. These studies have focused on the positive effects of cryogenic coo...

Concepts of Sustainable Machining Processes

Sustainable production as a global word, content important elements on all the fields as well as machining processes. Machining can be performed either on conventional or nowadays modern CNC way. Novel machining processes are based on CNC programmable technologies containing elements as CAD, CAM, etc. To define sustainable production as the creation of goods, using processes and systems, we hav...

Machining Processes for Precision Molds

INTRODUCTION The continuing drive towards miniaturisation in a number of industries including semiconductor, optoelectronic and medical is stimulated by requirements which include enhanced functionality, performance and reliability, increased energy efficiency, a cleaner environment, improved healthcare, together with reduced costs etc. [1, 2]. Also, new products for fastgrowing industries like...
