In addition, the machining file may be a manually input workpiece shape and machining hole site, or a trial machining file generated by the measurement control module 301, and meanwhile, both the machining file and the trial machining file may be stored in the common storage 50, wherein the measurement control module 301, the machining control module 302, and the common storage 50 are connected to each other in a signal communication manner, for example, in a signal communication manner of a wired or wireless network, but not limited to a network.
Next, referring to fig. 2, fig. 2 is a flowchart illustrating a process control module calibration of the integrated metrology process control system of the present invention. Fig. 1 is also referred to in the description of fig. 2. In this embodiment, first, in step a 01: the machining control module 302 performs a trial machining step according to the trial machining file. Next, step A02: the metrology control module 301 may be configured to test whether the trial machining error of the workpiece after the machining step meets a first error range, wherein the first error range is ± 0.05mm, but the first error range should not be construed as being limited to the embodiments set forth herein. If the trial machining error does not meet the first error range, performing step a 03: the metrology control module 301 performs a tool table calibration according to the trial machining error, and repeats steps a01 and a02 until the trial machining error meets the first error range. When the trial machining error meets the first error range, the step a04 is performed: the process control module 302 performs the processing steps according to the process profile. Next, step a 05: the metrology control module 301 may measure whether the machining error of the workpiece after the machining step is within a third error range, wherein the third error range is ± 0.05mm, but the third error range should not be construed as being limited to the embodiments set forth herein. If the machining error does not meet the third error range, performing step a 06: the measurement control module 301 performs real-time tool table calibration according to the machining error, and repeats step a04 and step a05 until the machining error meets the third error range. When the machining error meets the third error range, the method proceeds to step a 07: it is noted that the calibration process may only include step a01, step a02, and step a03, that is, after the trial machining error meets the first error range, the step a04 may be selected to be continued or the calibration is terminated.
