An Experimental Device for Measuring Cutting Forces of a Cutting Tool

In this paper, a soil cutting test rig was developed equipping with two force sensors and a displacement sensor. The equipment could perform measurements continuously at various cutting speeds when the cutting tools worked in the soils. The cutting tool is a rectangle blade. It can moves horizontally and cuts a soil sample at a selected angle. The forces and the displacement of the cutting tools can then be obtained by the sensors and recorded for future engineering use. Verification test was then conducted to determine the performance of the developed rig. Marine sediment soil was tested. The cutting resist force, vertical force and the relationship with respect to cutting distance can be measured and the new device can be used in the cutting machines in the future.
