1. Performing three dimensional measurements on micro-scale features using a flexible CMM fiber probe with ellipsoidal tip
Published: 1/5/2012
Authors: Balasubramanian Muralikrishnan, Jack A Stone Jr, Craig M Shakarji, John Richard Stoup
Abstract: The tip of a traditional CMM probe used for measurements of macro-scale artifacts is generally a sphere of excellent geometry. Its known diameter (from a prior calibration) and form along with the known approach direction (which is normal to the surf ...

2. Measuring Step Gauges Using the NIST M48 CMM
Published: 4/1/2011
Authors: John Richard Stoup, Bryon S. Faust
Abstract: The Moore M48 coordinate measuring machine (CMM) has provided NIST with flexible measurement capabilities for many years. The machine‰s state of the art performance was further improved following the move of the machine into the new Advanced Measurem ...

3. Micro-feature dimensional and form measurements with the NIST fiber probe on a CMM
Published: 7/30/2010
Authors: Balasubramanian Muralikrishnan, Jack A Stone Jr, John Richard Stoup, Chittaranjan Sahay
Abstract: The NIST fiber probe is a Coordinate Measuring Machine (CMM) probing system intended for diameter and form measurement of micro features and small holes. This Moore M48 CMM at NIST can measure holes down to 500 um diameter with the Movamatic probe; t ...

4. Measuring Step Gauges Using the NIST M48 CMM
Published: 7/25/2010
Authors: John Richard Stoup, Bryon S. Faust
Abstract: The Moore M48 coordinate measuring machine (CMM) has provided NIST with unique and very flexible measurement capabilities for many years. The machine‰s state of the art performance was further improved following the move of the machine into the new A ...

5. DIAMETER AND FORM MEASUREMENT OF A MICRO-HOLE IN A FUEL INJECTOR NOZZLE WITH THE NIST FIBER PROBE
Published: 11/2/2009
Authors: Balasubramanian Muralikrishnan, Jack A Stone Jr, John Richard Stoup
Abstract: We discuss the measurement of diameter and form of micro-holes with reverse tapers in a fuel injector nozzle using an ultra-low force contact fiber probe on a CMM. The fiber probe was designed and built at the National Institute of Standards and Tech ...

6. Area Measurement of Knife Edge and Cylindrical Apertures using Ultra Low Force Contact Fiber Probe on a CMM
Published: 1/1/2008
Authors: Balasubramanian Muralikrishnan, Jack A Stone Jr, John Richard Stoup
Abstract: Several radiometric and photometric measurements depend on high accuracy area measurement of precision apertures. Some apertures have sharp edges and are generally measured optically. At the Precision Engineering Division (PED) of the National Instit ...

7. Roundness Measurements Using the NIST Fiber Probe
Published: 1/1/2007
Authors: Balasubramanian Muralikrishnan, Jack A Stone Jr, John Richard Stoup
Abstract: We have described a fiber probe for dimensional measurement of micro-holes in the 2004 and 2006 ASPE annual meetings. In this abstract, we describe the adaptation of this probe for measuring roundness of tiny holes and knife edge apertures. In its cu ...
