The orthogonal cutting method of soft material with acrylic rubber and graphite was investigated by measuring the deformation of the material and the chip at several conditions in temperature. The experimented rake angle and temperature were 10, 30, 55 and 68 degrees, and -5, 0, 10, 15 and 20 degrees Celsius respectively. The mode of the deformation of the work during cutting changed from the shearing to hitting wedge mode at the rake angle higher than 55 degrees. The thrust force became negative at the higher rake angle. It was suggested that the increasing force to push up the work by the rake face. The tool with double-deck on rake face was found to be effective to control the thrust force. It was found that the surface of the chip become adhesive and rough with an increase in temperature. The chip was contacted on the rake surface of the tool widely at 20 degrees Celsius. It was suggested that that the increase of the friction force on the rake face result in rougher surface and more adhesive of the chip.
