Green Machining for Conventional P/M Processes

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...

Maps of Dispersions for Machining Processes

During product design, the design office defines dimensional and geometrical parameters according to the use criteria and product functionality. The manufacturing department must integrate the manufacturing and the workpiece position dispersions during the choice of tools and the machine operating modes and parameter values to respect the functional constraints. In this article, the authors sug...

Machinability of Sinter-hardening PM materials with experimental machining enhancers

Although powder metallurgy is an economical method for production of near net shape components, machining operations are often required to deliver desired geometrical features, dimensional tolerances, and surface finish of PM parts. Machining enhancers are used to improve the machinability of PM components and to increase tool life. MnS is the most common machinability enhancer used for PM stee...

Nontraditional and Hybrid Machining Processes

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...
