Title:
METHOD FOR MEASURING AND EVALUATING ERROR OF FEATURE LINE-BASED ARC CAM PROFILE
Document Type and Number:
WIPO Patent Application WO/2021/128614
Kind Code:
A1
Abstract:
Provided is a method for measuring and evaluating an error of a feature line-based arc cam profile, wherein the implementation steps of the method are as follows: constructing a four-axis measurement system with a three-coordinate measuring machine and a turntable; planning a feature line of the arc cam profile to be measured; measuring the feature points of the arc cam profile; establishing an error model of the arc cam profile measurement system; evaluating the error of the arc cam profile feature line; evaluating the error of the arc cam profile; the establishment of the error modeling of the measurement system effectively avoids the error influence of a detection device itself on a measurement result, and the use of segmented measurement and evaluation of the feature line error of the arc cam at a specified angle avoids the probe radius compensation, improves the measurement speed and calculation accuracy, obtain more accurate detection results, facilitate to improve the machining accuracy of the arc cam and formulate quality inspection standards.
