Method and system for measuring geometrical characters of a figure

A computer-based method for measuring geometrical characters of a figure, comprising the steps of:

• obtaining a figure of a workpiece;
• displaying the figure, which is constituted by different kinds of objects;
• keeping objects to be measured and deleting the other kinds of objects;
• marking the kept objects;
• measuring the marked objects, comprising the steps of:
• initializing the marked objects and confirming measuring points of the marked objects and coordinates of the measuring points;
• outputting DMIS (Dimensional Measurement Interface Specification) paths and converting a data format of the DMIS paths into a measure path;
• and
• determining a motion type of the measure path and invoking a corresponding motion;
• determining whether any mistake occurs during the measuring process;
• recording measure paths while measuring the marked objects if no mistake occurs during the measuring process;
• and
• storing the recorded measure paths as a program, which is invoked for automatically measuring other workpieces of the same kind as the workpiece.

A method for verifying and measuring geometrical characters of a workpiece figure, comprising the steps of:

• retrieving design information of a workpiece figure;
• simulatively displaying said workpiece figure according to said information;
• identifying measurable objects from said information of said workpiece figure;
• measuring said identified objects by means of measuring said simulative display of said workpiece figure, comprising the steps of:
• initializing said identified objects and confirming measuring points of said identified objects and coordinates of said measuring points;
• outputting DMIS (Dimensional Measurement Interface Specification) paths and converting a data format of said DMIS paths into a measure path;
• and
• determining a motion type of said measure path and invoking a corresponding motion;
• recording measure paths for measuring said identified objects so as to provide said measure paths for actual measurement;
• and
• recording said measure paths as an executable program, which is invoked for automatically measuring other workpiece figures of the same kind as said workpiece figure.
