You may experience issues viewing this site in Internet Explorer 9, 10 or The measure of the surface texture is generally determined in terms of its roughness, waviness and Form.

Deviations from the desired form result from clamping marks or sliding marks machining guide errors etc. Selecting a waviness filter will remove roughness elements,leaving the waviness profile for evaluation.

The notes below relate to the standards as listed above R a – Average Roughness Measuring Surface Finish In the past surface texture has been assessed by the judgment of the inspector either by eye or even fingernail.

Looks at methods for assessing surface texture of machined, self-finished and other surfaces, covering characteristics and parameters, terminology, preferred values for grading, sampling lengths and cut-off values.

It may result from such factors as machine cinish work deflection, vibration, chatter, heat treatment, or warping strains.

On the normal portable units the guide is generally based on a skid which slides over the general surface ensuring that the linked stylus moves in a straight line parallel to the local surface.

The surface is measured by moving the stylus across the surface. How does it work? Your basket is empty.

These Pages include various standards.

The evaluation was done by comparing the surface to be measured with standard surfaces A modern typical surface measuring instrument will consist of a stylus with a small tip diamond a gauge or transducer, a traverse datum and a processor. The default evaluation length “ln” consists of 5 sample lengths “lr. The Amber document status indicator indicates surfaec some caution is needed when using this ffinish – it is either: R z is the sum of the height of the highest peak plus the lowest valley depth within a sampling length lr.

The total roughness, R t R yis the sum of these two, or the vertical distance from the deepest valley to the highest peak.: Everything you need to know on one page.
