2020年4月18日 · H值的选择有两种方式，一种是绝对值方式，即H值实际距离的绝对值；另一种是相对百分数方式选定。 首先确定评定所需要的H值，然后，计算RPc峰计数值，一个高于H值的峰与一个相邻的低于H值的谷组成RPc峰计数值的一个数。 RPc是在评定长度上计算评定的，公式如下： 表示轮廓支撑率随水平位置而变的关系曲线。 在给定水平位置C上轮廓的实体材料长度与评定 …

Surface roughness testers, also known as roughness gauges, are portable and have a stylus with a small, smooth contact point for tracing the surface of a workpiece to measure minute irregularities. The surface measurements are displayed on the LCD screen.

A roughness tester traces a surface profile using a skid-type (contact-type) method with a tracer tip such as a diamond stylus and piezo-electric detection to calculate roughness. Common types of parameters include Ra (roughness average), Rv (maximum profile valley depth), and Rsk (skewness), and assessed profiles.

Starrett Surface Roughness Gages are precision instruments used for measuring the surface roughness of a variety of materials. With user-friendly software and advanced features such as Bluetooth connectivity and automatic calibration, these gages provide reliable and …

The most popular parameter is “Ra”. Ra is commonly defined as the arithmetic average roughness. While the Ra parameter is easy and efficient, there are other parameters that can be more specific and useful depending on the application requirements.

Trace the surface of a part to calculate its roughness parameters in Ra, Rp, and Rq. Move the thumb lever to quickly check the thickness of flat stock, pipe, or tubing. Measure the gloss of paint, coatings, and surfaces to ensure each product is as shiny as the last. Magnify your part to check for dimensional accuracy and surface defects.
