MASTERCLASS: MACHINING EXCELLENCE

FOR A COST EFFICIENT METAL CUTTING PROCESS

This Masterclass gives a comprehensive overview of the different physical models used to describe and analyse a machining process and of the basic mechanisms associated with it. A considerable number of practical models and guidelines are outlined. The aim is to provide an adequate understanding of the machining process in different types of workpiece material. Also, a link is made between machining technology, production economics and environmental impact. The primary purpose of this Masterclass is to give practical models to work towards a productive and cost-efficient metal cutting process that creates a minimum load on the environment. Most of the relationships, models and guidelines described have been verified experimentally in a wide variety of workpiece materials.

INTERACTION

The behaviour of the machining process is the result of an interaction between the shape and material properties of the workpiece, the geometry of the cutting tool and the properties of the cutting material, the characteristics of the machine tool and auxiliary equipment as well as the cutting conditions employed and the impact it has on the environment. To understand a metal cutting process and the interactions between all the different elements, it is crucial to have an insight into the process conditions which develop between the workpiece and the cutting edge. These process conditions are determined and described by the combination of the mechanical, thermal, chemical, tribological and environmental loads.

The interaction between the load situation during the cutting process and the properties of the cutting tool gives a certain tool wear which leads to a certain tool life. This defines a total amount of workpiece material which is removed by a cutting edge under given process conditions. These conditions result in a machining time required for finishing a workpiece with a certain quality, which in turn represents a certain manufacturing cost.

The aim is to facilitate knowledge sharing, networking and the demonstration of cost efficiency, productivity and continuous improvement trends, technology and innovations.

 

 

This Master Class focuses on managing directors, operations managers, heads of production, plant managers, manufacturing managers, engineering managers, senior engineers etc. who want to understand, control and work with the key indicators that are defining and guiding a controllable and reliable machining process.
