Abstract: An exemplary method for measuring workpieces is disclosed. The method includes the steps of: measuring a workpiece; recording the measuring procedures of the workpiece; generating procedure codes according to the measuring procedures; storing the procedure codes in a program file; generating a measuring program by compiling the procedure codes and saving corresponding procedure commands of the compiled program file in a measuring program command package; and measuring a same type of workpieces by executing the procedure commands of the measuring program command package. By utilizing the present invention, the same type of workpieces can be measured automatically, measuring time can be reduced, and measuring efficiency can be enhanced.

Abstract: A method for error compensation of a Coordinate Measurement Machine (CMM) includes the steps of: setting a mathematical mode; detecting errors of the CMM; compensating the errors; measuring a standard object on the CMM and obtaining measured values; calculating the deviation of the measured values and compensation factors of each axis; comparing the deviation of the measured values with corresponding precision standard and determining whether the precision of the CMM is acceptable. A related method is also disclosed. By utilizing the present invention, the error compensation can be achieved quickly, and measurement accuracy is improved.

Abstract: An identifying system (102) is provided for identifying a geometrical element in an image automatically. The image may be retrieved from an image capturing apparatus (101) and is imported in a coordinate system. The identifying system includes: a collecting module (1021) for collecting dots from the image as a dot muster and retrieving coordinates of all dots of the dot muster from the coordinate system; a curve fitting and geometrical element identifying module (1022) for curve fitting according to the coordinates of all the dots of the dot muster to identify what geometrical element the dot muster is; a storing module (1023) for storing the coordinates of all the dots of the dot muster, data produced during the curve fitting process, and result data of curve fitting and geometrical element identifying; and an outputting module (1025) for outputting the result data. A related identifying method is also provided.

Abstract: A system for measuring a figure of a workpiece includes an application server (2). The application server provides a hardware detecting module (200) for detecting hardware after system activation and for determining whether any mistake occurs. A mistake prompting module (201) is provided for sending a dialog box to prompt user to maintain the system. A measuring module (202) is provided for measuring the figure of the workpieces, and for comparing measuring results. A measuring result output module (203) is provided for outputting measuring results with text. A related method is also disclosed.
