The manufacture of individualised products in small quantities combined with short innovation cycles poses challenges for production technology. Reconfigurable production systems with flexible functionality and technology can be part of the solution. A novel concept for a modular machine tool includes interchangeable process modules and a flexible control system. The system is used for research in the fields of control, regulation and machine technology. Description of the machine The machine consists of a fixed basic structure for positioning and aligning the machine table. This consists of a welded frame that holds the control cabinets and drive technology for the basic structure and on which the base plate rests. On the base plate is an X-Y axis structure with machine table, consisting of a clamped rack and pinion drive (RPD) and a ball screw drive (BSD). A rotary swivelling unit can also be attached to the machine table. There are 3 process modules for 3D printing, milling and processing using a laser scanner. An HMI for machine control is installed at the front right, a 32-inch panel for displaying RPD measured values is located on the left and a 70-inch touch monitor for the split presentation ‘Additive manufacturing’ and ‘Mechanical design’ is located at the rear. 

• The main aim is to combine different manufacturing technologies and research into innovative control approaches for linear technology. To this end, a modular approach is pursued, which is realised in the form of interchangeable process modules.
• Control technology research topics such as multi-axis path planning for laser, inkjet and milling processes.
• Control technology approach to increase the accuracy of indirectly controlled, electrically tensioned rack and pinion drives
