Dynamometers for cutting processes optimization in research and machining development

Cutting force measurements with dynamometers

Whether operators want to develop new cutting force processes or improve existing ones, cutting force measurements are front and center: In both research and machining development, they provide crucial data for matching equipment perfectly to the cutting process. The data provides information on the tool’s influence on the cutting force as well as information about the cutting process itself.

This is where stationary and rotating dynamometers from Kistler come in: The piezoelectric sensors measure cutting forces during the machining process with high accuracy. Based on the acquired figures from dynamometers, operators can evaluate and choose the optimal tools, clamping devices, cooling lubricants and materials for their cutting processes. This way, the data helps boost the quality and cost efficiency of the tools and cutting processes as well as extend the tools’ lifetime.

Also, Kistler’s dynamometers enable operators to examine and optimize raw materials: They deliver information about the characteristics of materials, which in turn allows their evaluation with regards to the cutting processes. The data can also help verify individual simulations and process models or be used to establish unique product features.

Thanks to the high natural frequency of the MicroDyn, the TU Dortmund can measure highly dynamic forces at spindle speeds of up to 160,000 rpm

Kistler's compact dynamometers for cutting force measurement can be easily integrated into cutting tools.

The piezoelectric dynamometers from Kistler have a high durability and are built to be resistant to cooling lubricants. This way, operators can make use of their extensive life cycles.

Extensive measurements of individual cutting-edge engagements

Piezoelectric cutting force measurement technology can resolve individual cutting-edge engagements. The sensors measure forces with high precision – even for highly dynamic processes and at maximum speed.

Tool development and assessment

Kistler provides measurement technology for tool development and tool assessment.

Data acquired via piezoelectric sensors can be used to optimize tools and clamping devices, to evaluate cooling lubricants and to determine how easily material can be machined. The data can also help adapt the processes and tools in use to maximize tool life. With the help of the dynamometers, operators can analyze unfavorable cutting situations, identify influences in the process due to different material batches and discover unused potential in tool productivity.

Analysis of cutting forces and process optimization

Dynamometers help analyze cutting forces and optimize the processes

In addition, dynamometers help analyze cutting processes via targeted troubleshooting: They measure the cutting forces at work with high precision and record them with the force resolution related to every individual cutting edge tool. The generated data can serve as a base for operators to adapt their cutting processes and optimize them for maximum efficiency and yield.
