I am in process of implementing an Oasis Vision Inspection system for inspection of small threaded fasteners. We had previously decided to move forward with validation of each program by alternative inspection methods (micrometer, caliper, etc) as each program is created individually. If the program is then copied and only one dimension changed then that one dimension within the program would be validated. The programs are set by creating the appropriate feature box and then identified tolerances. An actual measurement is reported with pass of fail based off the tolerance. As we are progressing through the creation of programs the question has arisen as to whether each program requires the validation or whether top level features can be validates such as diameters, lengths etc. How are others managing this requirement? We currently do not have any customers which have tight software controls however we looking to more strongly enter that market and I do not want to back track on the programs already created.
