Abstract
The paper argues the necessity of 3-dimensional inspection of injected plastic parts, presenting the special demands and particular condition related to the specificity of part material nature. A measuring strategy on the coordinate measuring machine is presented for verifying the position, dimensional accuracy and shape of the circular holes, slots and the line form for plastic parts used in the automotive industry due to the dimensional changes caused by shrinkage and warpage. The reverse-engineering technique applied in the try-out phase to the production launch is also presented. Keywords: injection, shrinkage, warpage,3-D measurement, reverse engineering
