TESTING SYSTEM FOR FLATNESS AND PARALLELISM
First Claim
1. A testing system for testing flatness of a surface of a workpiece, comprising:
- a testing apparatus including a testing box and a measuring apparatus;
the testing box including a plurality of holders, the holders defining a datum plane;
the measuring apparatus comprising a plurality of movable testing poles extending out of the testing box and a plurality of gauges configured for measuring distance of the testing poles retracting into the testing box, ends of the testing poles away from the testing box being located at the datum plane and configured for supporting the surface of the workpiece thereon to allow the gauges measuring retracting distance of the testing poles under the pressure of the workpiece, the retracting distance of the testing poles being equal to distances between testing points on the surface of the workpieces and the datum plane; and
a processor being connected to the testing apparatus for receiving and processing testing data which are converted from the retracting distance of the testing poles measured by the gauges.

Abstract
A testing system for testing flatness of a surface of a workpiece includes a testing apparatus (10) and a processor (20). The testing apparatus includes a testing box (12) and a measuring apparatus (14). The testing box includes a plurality of holders (122); the holders define a datum plane. The measuring apparatus comprises a plurality of movable testing poles (142) extending out of the testing box and a plurality of gauges (141) configured for measuring distance of the testing poles retracting into the testing box. Ends (1421) of the testing poles away from the testing box are located at the datum plane and configured for supporting the surface of the workpiece thereon to allow the gauges measuring retracting distance of the testing poles under the pressure of the workpiece. The retracting distance of the testing poles is equal to distances between testing points on the surface of the workpieces and the datum plane. The processor is connected to the testing apparatus for receiving and processing testing data that are converted from the retracting distance of the testing poles measured by the gauges.

14. A testing method for testing flatness of a surface of a workpiece via a testing system which comprises a testing box and a processor, the testing apparatus comprising a plurality of movable testing poles ends of which locate at a datum plane, the method comprising steps of:
-
setting testing parameters in the processor; placing the workpiece on the testing poles to cause the ends of the testing poles respectively contacting with testing points on the surface of the workpiece so that some of the testing poles corresponding to the testing points which locate under the datum plane partly retract to the testing box under the pressure of the workpiece; recording the retracting distances of the testing poles and converting the retracting distances into testing data; outputting the testing data to the processor; and the processor generating test results via comparing the testing data with the testing parameters. - View Dependent Claims (15, 16, 17)
