INSPECTION AND MEASURING APPARATUS AND METHOD

A system writes computer instructions and statements for a program which operates on manufacturing apparatus to measure objects processed in the apparatus and to approve and select or reject the reviewed and measured objects in accordance with parameters established by an optical system. This optical system on sensing an inspected object forms an image on a photosensitive RAM and this information relating to the image is sorted in an electronic system. The image information, which is transmitted in bits, and the operation selects and approves objects which are detected as being within a predetermined average deviation in these dimensions. The information on the predetermined range of dimensions is established from a representative number by the data of objects on the object edges that determine height, width and length, which data is initially sensed by the optical system, is transmitted in digital form and stored. In the selection process bits from the sensing of the inspected object are read from the RAM and compared with stored product data. If a significant difference is detected the inspected object is rejected.
