TRR 96 Thermo-Energetic Design of Machine Tools

 

Background

Currently investigated measures in the area of energy-efficient chipping production aim at preventing dissipation losses which are not directly involved in the process of chip formation.

Such losses are dissipated as thermal flows. These thermal flows and the principally lossy operation of coolant-lubricant cycles, however, contribute to the stabilization of the thermoelastic behavior of machine tools.

For this reason, they also assure production accuracy. Especially regarding productive processes with high time chipping volumes and high accuracy requirements, the thermoelastic stabilization effect of these basic load thermal flows is virtually indispensible.

Therefore, what needs to be addressed is a conflict of objectives in the triangle of energy input, efficiency and productivity.

Aims of the SFB/Transregio

The scientific objective of the SFB/Transregio is to resolve this conflict of objectives by investigating and implementing solutions that allow an accurate chipping conditioning under energy-efficient production conditions.

The two subprojects

B03 'Investigation of Component and Assembly Groups' and
B06 'Correction of Load Dependent Machine Tool Deformations Based on Property Models'

are conducted at the Chair of Machine Tools of the Laboratory for Machine Tools and Production Engineering (WZL) at RWTH Aachen University.
