Assessment of geometric features such as roundness, flatness, and straightness to ensure part conformance.
A portable robot arm CMM (Coordinate Measuring Machine) is a lightweight, articulated measuring arm which aids in performing 3D measurements, on the shop floor, in inspection labs, or in field applications.
Roundness and cylindricity can be measured using two general types of measurement: 2. An extrinsic datum can be provided by a precision spindle that serves as a reference. The following are examples of using an extrinsic datum:
Straightness and flatness are basic form tolerances that can be measured using simple hand gages or more complex and precise electronic instruments:
A coordinate measuring machine (CMM) provides precise measurement of the dimensions and geometry of physical objects. A probe or sensor detects points on the object’s surface, and the 3D position of each point is recorded. From this point cloud, the object’s features can be mapped in relatively high resolution, and dimensions can be extracted for product design, quality…
