Precision machining is an important aspect of manufacturing high-precision and complex parts. This advanced manufacturing process is essential in a variety of industries, including aerospace, automotive, medical and electronics, where either very small tolerances and/or surface finish quality are required. Increasing competitiveness in this area requires continuous technological advances related to the development of applications and strategies for high-precision manufacturing adapted to specific production machines. The research focuses on achieving manufacturing precision in the micrometer range for grinding machines or tens of micrometers for other CNC machines.

The members of the research group are multidisciplinary and include experts from all relevant departments of the Institute of Production Machines, Systems and Robotics as needed.

Research topics:

• Digital Transformation of Industry and Industry 4.0.

• Development of algorithms for monitoring the state and condition of the machine and supporting its maintenance.

• Real-time evaluation of the process.

• Application of lasers to improve machining accuracy and performance.

• Monitoring, simulation and optimization of the machining process using AI.

• Development of new methods and equipment for precision measurement.

• Improving the quality of machined parts.

• Machine load force analysis during machining.

Examples of solved projects:

• Technologies and tools for the digital transformation of engineering

• Research and development of a machine tool monitoring unit to support proactive maintenance

• National Centre of Competence in Mechanical Engineering

• Machine Tools and Precision Engineering

• LEVEL-UP – Protocols and Strategies for extending the useful Life of major capital investments and Large Industrial Equipment.

• Support of development of fully satisfying machines
