An apparatus for testing a razor blade comprises a base, a material support table, a material sample, a transport carriage, a blade retention assembly, and a razor blade. The material support table is supported by the base. The transport carriage is movably coupled with the base and is movable with respect to the material support table between a start position and an end position. The blade retention assembly is movably coupled with the transport carriage and is movable with respect to the material support table between a blade-engaged position and a blade disengaged position. The blade retention assembly is movable together with the transport carriage between the start position and the end position. The blade is releasably attached to the blade retention assembly. The razor blade contacts the material sample when the blade retention assembly is in the blade-engaged position. Methods are also provided.

The mounting jig assembly includes a jig body and a clamp assembly. The jig body includes a top surface, a bottom surface, a front wall, a rear wall, and a pair of side walls. The jig body is configured to support the test component on the testing assembly with the test component in contact with the top surface and the bottom surface in contact with the testing platform. The jig body defines an elongated opening that extends between the top surface and the bottom surface. The top surface being oriented obliquely with respect to the bottom surface. The clamp assembly is moveable between a clamped position and an unclamped position. In the clamped position the clamp assembly inhibits movement of the test component with respect to the jig body. In the unclamped position the clamp assembly permits movement of the test component with respect to the jig body.

A cutting insert for cutting, milling or drilling of metal includes a body having an elongate recess extending along at least a portion of the body, a first layer covering interior side walls of the recess, and a sensor arrangement. The body includes a substrate. The sensor arrangement includes sa lead extending along the recess. The lead includes electrically conductive material, which is arranged in the recess such that the first layer is located between the electrically conductive material and the substrate. For at least a depth below which at least a portion of the electrically conductive material is arranged in the recess, a width of the recess measured at that depth between portions of the first layer covering opposite interior side walls of the recess is less than or equal to 80 micrometers.

A method is provided. An actual fatigue curve limit is determined for actual stress of a drilling component based on an actual yield strength of a material of the drilling component. A plurality of drilling parameters is simulated for the drilling component to determine one or more estimated stresses enacted on the drilling component for one or more combinations of the plurality of drilling parameters. A component life cycle of the drilling component is determined based on the actual fatigue curve limit and the plurality of drilling parameters. A consumed component life of the drilling component is determined for an actual drilling step utilizing the drilling component, and a remaining life of the drilling component after the actual drilling step is determined.

A method for testing cutting performance of a diamond saw blade, relating to a technical field of diamond tool test, is provided, which solves problems of inaccuracy and non-uniformity existing in conventional methods for testing cutting performance of a diamond tool. The method includes steps of: (1) obtaining a set load parameter value, particularly including steps of: controlling a feed amount of the diamond saw blade; finding out a load value K corresponding to a maximum feed amount of the diamond saw blade on a cutting object; and setting M=0.70K-0.85K, wherein M is the set load parameter value; and (2) during cutting, controlling a cutting load value of the diamond saw blade to be 0.90M-1.1M through a servo system. Therefore, uniform three cutting elements of machine and tool, object, and feed thrust are realized, and the performance of the diamond tool is automatically and accurately measured.
