Abstract
Abstract The invention is an appratus for, and the method of clamping flexible items in a fixed position in relation to the measuring probe of a coordinate measuring machine. A perforated rigid plate is attached to the working surface of coordinate measuring machine. One or more hollow, rigid article holders are mated to the plate by use of suitable fastening mechanisms. On the upper end of each hollow support holder for articles is a flexible suction cup. A source of vacuum is provided to the article holders which is directed through the opening of the suction cup. One or more stand-offs or spacers may be installed on the plate as well, to help position a part. A part to be measured is then placed on the article holders and a vacuum is applied. Coding of the position of each of the perforations on the plate allows for easy set-up and reproducibility. The stand-offs or spacers are equipped at one end with a mechanism to allow attachment to the plate, and at the opposing end with a mechanism to allow mating of the stand offs or spacers together, or mating of them with the article holders. In this fashion, the stand-offs or spacers can function to change the height of the article holders in relation to the surface of the plate, and can also function to restrict the movement of the article placed on the invention. The method herein described includes the method of utilizing the features of the invention to affix an article to a accordinate measuring machine with good reliability and reproducibility.
