Determining cutting force coefficients from instantaneous cutting forces in ball end milling
International Journal of Machining and Machinability of Materials, 2016The precise prediction of cutting forces helps in improving the machining performances. This involves the modelling of cutting force components in tangential, radial and axial directions and determination of respective specific cutting force coefficients. In the present work, an improved method of identification of specific cutting force coefficient is

Intermittent metal cutting at small cutting depths—2. Cutting forces
International Journal of Machine Tools and Manufacture, 1988Abstract Cutting forces in intermittent metal cutting at small cutting depths were investigated by single edge experiments. Single cutting strokes were performed in a modified Charpy pendulum tester which offers cutting and thrust force measurement and accurate selection of cutting speed and feed in ranges typical for many intermittent high speed ...

Cutting force modelling and physical cutting simulation
1998There is a direct relationship between the cutting conditions and the economics of the SSM-process. The goal is to cut the part as quickly as possible while maintaining safe cutting conditions and high part quality. The simulation of the physical process must be capable of estimating the cutting forces.

Study of Soft Tissue Cutting Forces and Cutting Speeds
2004A versatile equipment to study the cutting of soft tissue with surgery scalpel was designed and constructed. Experiments were performed with pig liver (ex-vivo) to measure the blade-tissue interaction forces at cutting speeds ranging from 0.1 cm/sec-2.54 cm/sec. The experimentally measured force-displacement curves reveal that the liver cutting process

Cutting Force Model for Diamond Cutting Microstructured Surfaces
Applied Mechanics and Materials, 2013The depth of cut changed periodically along the contour of the cutting surfaces. The diamond tool of sharp point tip was used in diamond cutting microstructured surfaces with Fast Tool Serve (FTS). All reported the cutting force model were not suitable for accurately predicting cutting force.
