Cutting Forces During Turning

Cutting Forces during Turning   

Technical Description of Cutting Forces during Turning  

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.
