Sustainable machining is the finishing of competitively priced products, which meet the needs of customers and which give total quality in the product life cycle, gradually reducing environmental impact and raw material and energy use throughout the life cycle and in the production chain to a level than at least is in balance with the carrying capacity of the planet.

This Masterclass focuses on every company facing the problem of small batch production of diverse workpieces in a rapidly changing world. Each company has an economic, social and environmental responsibility in addition to the classic business elements of cost control, productivity and quality. In every machining company, sustainable business starts with sustainable machining.


For a manager, it is important you have a good understanding of the core indicators (costs, productivity, quality, output, environmental foot print) that determine the efficiency and sustainability of your business.

An insight into and understanding of key indicators that determine the ‘health condition’ of the company is a first important step. From this understanding, concrete and correct decisions can then be taken regarding the ‘pain points’ and how best to address them.

The core in every machining company is the machining processes and systems. The challenge is to manage your machining processes in a reliable, cost-efficient, productive way, with minimal energy consumption and environmentally damaging emissions from waste products. In addition to the actual machining process, of course, it is also important that your production organisation is efficient and how effectively your people contribute to your success as a company.

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



This Masterclass focuses on managing directors, operations managers, heads of production, plant managers, manufacturing managers, engineering managers, senior engineers etc. who want to understand and control the key indicators that are defining and guiding a sustainable machining process and system; as well economical, human and environmental sustainability.
