Objective
The integration of high precision 3D-shape measurements of workpieces into a computer integrated manufacturing (CIM) production line will be of increasing importance within the next few years. Although various potentially well-suited optical measuring techniques have been developed they suffer considerable constraints with regard to the range of measurement, the measuring time, the flexibility with respect to different workpieces and their overall cost. These problems which have prevented the economic introduction of such systems into a CIM environment can in principle be solved by the use of a modular, computer-aided system architecture. In order to obtain the utmost versatility as a key to low cost solutions both software and hardware will have a modular system structure and the measuring techniques will provide both comprehensive topographic 3-D shape information and the required resolution, measuring range and dynamics.
The objective of the project is to determine the feasibility of a modular, computer-aided 3D-shape inspection system within a CIM environment, thereby taking into account the application of the inspection system in industry together with the industrial requirements and specifications.
The inspection system shall make use of optical topographic measuring techniques. Two classes of workpieces to be measured shall be considered, mainly made from metal, ceramics and plastics: objects with diameters of up to 100 mm to be measured with an accuracy between 0.5 um and 2 um and objects with diameters of up to 1000 mm to be measured with an accuracy between 2 um and 100 um.
In order to determine which optical techniques are most suitable for such an inspection system a literature study and a theoretical analysis of techniques based upon the moire principles, diffraction pattern techniques, opto-mechanical scanning and sampling techniques will be carried out in the first part of the project (6 months). This shall be followed by an experimental study (6 months) to clarify possible remaining questions.
Status:
In progress.
