The introduction of advanced technology coordinate measuring systems such as digital theodolites, photogrammetry, and coordinate measuring machines into the aerospace environment has created many application opportunities to meet the challenge of high quality components produced in an internationally competitive market with the associated short schedules. One key application is the conversion from gages to coordinate measuring system for periodic inspection of tooling. To effectively accomplish this task requires not only a major cultural change, but also technically competent people, latest technology measurement equipment, management support, and a sound logical plan for the conversion implementation process. The objective of this paper is to outline with conversion plan describing standardization through management decision making in conjunction with individual tool conversion plans.
Many hurdles which present themselves in introducing computer based coordinate metrology into traditional gaged based tooling are addressed and put aside. Among some of these issues are:
These issues and others are solved through decision making and standardization, and are presented to the reader. By emphasizing preplanning prior to manpower and equipment commitment, conversion process problem can be resolved in a timely and efficient manner.
- To what extent should tool design reflect coordinate metrology targeting requirements?
- Should old tool designs be altered?
- Can gages be eliminated completely from a tool family?
- What type of targeting should be used to best support digital theodolites, photogrammetry, coordinate measuring machines and conventional optics?
- How are interchangeability requirements met utilizing coordinate metrology techniques?
- Which programs and tools should be selected for conversions?
- What coordinate measuring system should be used on what tools?
- What correlation techniques are employed for the comparison of conventional documentation with the new coordinate metrology documentation?
