All you Need to Know about Portable CMM Arm Measuring Tool

A portable Coordinate Measuring Machine (CMM) arm is a precise measurement tool used to inspect the dimensions and geometry of manufactured parts and products. It is an important tool for quality control in manufacturing and is commonly used in the aerospace, automotive, and medical device manufacturing industries.

A portable cmm arm measuring consists of a series of interconnected joints and a probe used to touch and measure the surface of an object. The probe is connected to the CMM arm via a series of sensors and encoders that measure each joint’s movement and the probe’s orientation. The measurements taken by the CMM arm are then sent to a computer, where they are analyzed and compared to the desired dimensions of the part being inspected.

Advantages of a portable CMM arm

Accurate Measurements

This is one of the main advantages of a portable CMM arm. It can quickly and accurately measure parts and products in various locations. It can measure dimensions within a few microns, making it ideal for use in applications with high accuracy. This makes it a valuable tool for quality control and ensuring that parts meet the required tolerances and specifications.


Unlike traditional CMMs, which are stationary and require the parts being measured to be brought to them, a portable CMM arm can be easily transported to the location of the part. This makes it ideal for manufacturing environments where parts may be located in different facility areas or floors.


A portable CMM arm is also faster and more efficient than other measurement tools, as it can simultaneously take measurements at multiple points. It is also less prone to operator error, as the measurements are taken automatically by the CMM arm rather than manually by an operator.

There are several different types of portable CMM arms on the market, each with unique features and capabilities. Some portable CMM arms are designed for use in confined spaces or environments with limited access, while others are designed for use in more open areas. Other portable CMM arms are equipped with specialized probes and sensors for measuring specific features or materials, such as surface roughness or conductivity.

How to Use a Portable CMM Arm

Using a portable CMM arm is a simple process. First, the CMM arm is set up at the location of the measured part, and the probe is calibrated. The operator then moves the probe to various points on the part’s surface, and the CMM arm takes measurements at each point. The measurements are then analyzed and compared to the desired dimensions of the part, and any deviations from the desired dimensions are identified and recorded.

A portable cmm arm is a valuable tool for manufacturing quality control, providing fast and accurate measurements of parts and products in various manufacturing locations. It is highly accurate, efficient, and easy to use, making it an essential tool for ensuring that manufactured parts meet the required specifications and tolerances.
