摘要： There is provided a measuring device that is inexpensive and easy to use, yet provides sufficient accuracy and resolution in continuous scanning measurement to measure workpiece surfaces. A dial gauge includes a spindle provided to be movable reciprocatively in an axial direction through a main body case. The main body case includes a stem provided to protrude from a side face of the main body case. A ball bearing that bears the spindle is provided inside the stem. A workpiece and the dial gage are relatively moved while a contact point at the tip of the spindle is in contact with the surface of the workpiece, and continuous scanning measurement is performed to measure irregularities of the surface of the workpiece or the amount of runout of the rotating workpiece.

摘要： A surface profiler including at least one front support wheel and at least one rear support wheel for travelling along the surface of a profile to be measured, the rotational axes of said wheels being longitudinally spaced, and the wheels contacting the surface being profiled in a collinear manner. A frame carried on the wheels carries at least one inclinometer and at least two vertical distance measuring apparatus such as lasers, and may also carry an optical encoder. The lasers are collinear with each other and with the wheels. Incremental to measurements of inclination angles provided by the inclinometer, together with incremental measurements of distance to the surface being measured provided by the lasers, produce a continuous, high resolution mathematical series of elevations representing the surface profile, including reproduction of surface features that are smaller than the distance between the wheels.

摘要： A system and a method for uniformed surface measurement are provided, in which a sensor is provided to perform measurements on a carrier in a polishing machine, and a measuring trajectory of the sensor on the carrier is adjusted by controlling the pivoting of a sensor carrier carrying the sensor and the rotation of a rotating platform in the polishing machine in order to achieve uniformed surface measurements of the carrier and real-time constructions of the surface topography. This allows the polishing state of the carrier to be monitored in real time, thereby improving the efficiency of the polishing process. A sensing apparatus for uniformed surface measurement is also provided.

摘要： A profiling machine includes an inclinometer and a displacement sensor. The inclinometer is configured to sense an incline of the profiling machine on a surface relative to the acceleration vector of gravity. The displacement sensor is configured to sense the distance that profiling machine has traversed along the surface. The profiling machine is configured to calculate and generate a surface profile of the surface based on incline data from the inclinometer and displacement data from the displacement sensor.

摘要： A cutting force analyser is provided, comprising weighing means adapted to determine the weight of an object and force applied to the object; a record of a force threshold for cutting the object; and indicating means. The analyser is formed to use the weighing means to differentiate between the weight of the object and cutting force applied to it, to compare the cutting force with the force threshold, and to use the indicating means to communicate how the force compares with the threshold.

摘要： A flatness sensing device includes a pressure sensing unit and a controller. The pressure sensing unit includes a plate portion, and a pressure sensor fixed and exposed at an edge of the plate portion. A sensing surface of the pressure sensor is flush with the bottom surface of the plate portion. The pressure sensor senses a pressure or lack of pressure of an object to be tested when it touches the object to be tested. The controller receives the pressure value output from the pressure sensor and determines a flatness of the object to be tested, the controller can issue an alarm on finding non-flatness and cause the degree of flatness to be displayed to a user.
