Roundness Measurement

Professional Roundness Measurement Services

Roundness, or circularity, is the 2D tolerance that controls how closely a cross-section of a cylinder, sphere, or cone is to a mathematically perfect circle. Consider a cylinder whose purpose is to roll along a flat surface. A small flat on the OD of the cylinder would detract from how smoothly the shaft can roll. The flat spot can even be so large that the shaft cannot roll at all. In this case the flat represents a deviation from a perfect circle that can be measured quite accurately.

An example of a more complex roundness error is called lobing, which is an unintended form error from a centerless grinding operation. Roundness callouts on drawings have no reference to a datum, as roundness does not relate to the cross-section’s location on the part.

The actual measurement of these parameters can be quite complex. They require the proper selection of reference elements and filtering techniques, which help in interpreting the collected data. This complexity is why it’s always recommended to work with a professional for roundness measurement or other metrological services. A company like Cross Precision Measurement.

Accurate Inspection and Circularity Measurements

The precision measurement group at Cross offers roundness measurement services at several locations throughout our network of ISO 17025 accredited inspection laboratories. Our technicians have years of experience working with a variety of part types and are ready to help you find the measurements you need to ensure your parts are within tolerances.

We believe our customers should be able to trust the measurements and readings produced by their machinery. Being able to trust your process is an important component in production forecasting, revenue estimation, and staffing estimation.

Benefits of Accurate Roundness Measurement

For many manufacturers, roundness measurement is a vitally important part of the quality assurance and control process. Accurate measurements of roundness have only become more important as the complexity of the production line has increased. As we see parts becoming more complicated, we also see tolerances shrink. These are cases when extremely precise roundness measurement instrumentation is needed. More than that, precision measurement instrumentation that can be trusted and verified.

As complexity rises, the need for precision in production also rises. When parts are off (even slightly), that deviation can cause problems for the production process, negative feedback from end users, or part failure down the line. Accurate roundness measurement machinery prevents problems like this and prevents potential catastrophic failure by detecting problems early. That way, adjustments can be made quickly without risking recalls or negative feedback.

Being able to identify problems early in production is an invaluable benefit for industrial operations. Avoid headaches and maintain both your reputation and competitive edge with reliable roundness measurement equipment inspection from Cross.
