A test and control software of the measuring machine based on single-flank testing for fine-pitch gears is programmed based on Visual C++.Two circular gratings are used to measure the angle of spindles
a capacitance displacement sensor is used to measure micro-displacement
a motion controller of ACR9000 is used to control dual-motor synchronous drive
and a data acquisition card of PCI 1784 is used to acquire data.Main functions of the software include parameter inputting
electric control
automatic measuring
data acquisition
deviation calculation
results saving
and inspection report and print.In addition
the inspection results indicate that the software has high stability
friendly man-machine interface and operating convenience.It can be applied to inspect the transmission error of fine-pitch gears.
