DESCRIPTION
Technical Description
Investigation of cutting forces during turning is fundamental to the teaching of cutting techniques.The setup 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
- influence of the cutting geometry of the lathe tool
