Stylus Tip-Size Effect on the Calibration of Periodic

metrology affects the measured surface geometry and surface roughness parameters. Typically an increase in the size of the stylus tip will result in a reduction in the measured roughness average (Ra) due to the tip's inability to contact the bottom of sharp valleys on the surface.

Geometric Dimensioning and Tolerancing (GDT)

Dec 25, 2015GDT is a symbolic language on engineering drawings that explicitly describes nominal geometry and its allowable variation. The need for precise communications developed the engineering drawings to the geometric dimensioning and tolerancing, which departs from the limitations of coordinate dimensioning.

Surface Roughness Texas AM University

Surface Roughness. It should be clearly understood that all surfaces have roughness, whether one can physically see it or not. Most of the surfaces that we consider to be smooth, such as the faces of a compact disc, have significant roughness when viewed at the right scale (micro- to nanoscale).

Drill Tool Geometry 371 toolingu

Improper drill tool geometry leads to premature tool wear and failure, poor surface finish, and slower speed and feed rates. Poor drill geometry can also cause deflection, which creates holes at incorrect locations and with poor tolerance. These issues increase manufacturing costs, create waste and scrapped parts, and slow production rates.
