The resultant error depends on the design and process tolerance associated with the locating surface when design references are selected for location.
For example, Abrasive-Form will know that a part can be done with CE but what's not known is that the part could be done three times faster if it was provided with a more qualified locating surface, or if there were a provision for a clamping surface that could be machined away later,
Liquid Penetrant--Liquid penetrant inspection is a very sensitive process for locating surface defects in metals by the observance of highly visible liquid that penetrates exposed openings such as cracks, tears, pits, laps and into porous surfaces.
Traditionally, a nonfunctional surface (such as a counterbore) is machined into the part as a locating surface. Using the dome and ring lands for location creates three major benefits:
The relationship between part features can be quickly determined without regard to a reference or locating surface. The gage measures external, internal, and distance dimensions, as well as perpendicularity, flatness, straightness, centers, and diameters.
Clean parts, especially with sealing and locating surfaces, are a key component of product performance and successful end products.
A scenario is a spatial type comprising a way of locating surfaces, features and so forth in relation to an origin (e.g.
All locating surfaces are precision ground to assure extremely close tolerances, and the manufacturing process ensures each collet will have a TIR of 0.0005" or less.
Irregularly shaped parts, extremely small, slender, or short and stubby parts or very large workpieces are another matter as are workpieces that require special locating surfaces.
This method is recommended for small lot runs, precise tolerances, heavy stock removal, holding relationships to other locating surfaces, or for larger parts not suitable for other disc grinding methods.
Access to datum surfaces for part alignment, and the position of locating surfaces that support the part, will also influence part orientation.
