Design and construction of a dynamometer for measurement of cutting forces during machining with linear motion

Considerable studies concerning cutting force measurement and its analysis in the past have been tackled by many researchers and organisations. As a result, many dynamometers were developed. Work to date has shown that most of these dynamometers are for turning and milling. In this study, a dynamometer has been designed and constructed using bending beam type load cells for shaping. Cutting force measurement tests on St 44 steel workpiece material during shaping have been performed. The obtained results were compared to the theoretically calculated ones, and a good agreement between the experimentally obtained and theoretically calculated results were seen. Therefore, the ‘1,1 coefficient’ used in the theoretical calculation of cutting forces during shaping was experimentally verified. This system is considered to be of vital significance as it enables the researchers to investigate the effect of rolling direction on the machinability of materials.
