Summary:
There are a number of industrial applications such as in the aerospace and disk drive industries, which require precision measurement of small diameter holes with high aspect ratio. Some of the standard measurement systems, such as optical techniques, while capable of characterizing holes on the surface of the work piece, would face difficulties in characterizing the interior of a hole especially if the latter is a non-through hole. A novel vibroscanning method has demonstrated the possibility measurement of a 125um micro hole with level of precision better than 0.5um [1,2]. However, this technique requires a special probe, which is not widely available. Because of this, CMM using mechanical probe is still commonly used in industry. However, using CMM for small hole measurement has certain drawbacks. It is expensive, time consuming, and is a contact measuring technique. Also it is difficult to use CMM for the measurement of very small diameter holes. Therefore it is desirable to develop an alternative, more widely available cost effective precision approach.
