FT 102 Cutting Forces during Turning
Education / GUNT Hamburg / Mechatronics / Manufacturing Engineering /

Investigation of cutting forces during turning is fundamental to the teaching of cutting techniques.The set-up comprises a transducer, which also holds the lathe tool, and an amplifier unit with digital displays. The forces that act on the lathe tool during machining are measured in three directions: cutting force, feed force and passive force. The 3-component force measurement device uses a strain gauge system. The amplifier unit supplies the strain gauge bridges and displays the measured values on three digital displays.
  The experiments must be conducted in a workshop environment, as a suitable lathe is required. 
  The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.


Learning Objectives / Experiments

- Measurement of forces in turning
  * influence of rotational speed, rate of feed, feed motion, lubrication and cooling conditions
