  • Patent number: 11846932
    Abstract: A part processing planning method includes the following steps. Firstly, a specific tolerance of a nominal size of a part is obtained. Then, a predetermined tolerance of each of processes is obtained. Then, using a process dimension chain establishing technique, at least one predetermined tolerance associated with the specification tolerance from the predetermined tolerances is obtained. Then, at least one predetermined tolerance associated with the specification tolerance is accumulated to obtain a size cumulative tolerance. Then, whether the size cumulative tolerance meets the specification tolerance is determined. Then, at least one predetermined tolerance associated with the specification tolerance is re-allocated when the cumulative tolerance does not meet the specification tolerance, such that the size cumulative tolerance is within the specification tolerance.

  • Patent number: 9835449
    Abstract: A surface measuring device includes a rotary platform, a shifting lever, a measuring module, and a control module. The rotary platform carries an object under test and rotates the object under test at a rotating speed. The shifting lever is above the rotary platform. The measuring module disposed on the shifting lever moves to measurement positions on the shifting lever and performs a surface height measurement at a sampling frequency to sampling points on a surface of the object under test when located at one measurement position. The control module selectively adjusts the rotational speed for the rotary platform or the sampling frequency for the measuring module according to the measurement position of the measuring module on the shifting lever in order to fit a distance between the sampling points on at least one part of the surface of the object under test to a sampling rule.
