Dimensional Inspection and Analysis

Dimensional Inspection and Analysis

Dimensional inspection and analysis are processes that involve measuring and evaluating physical components to ensure they meet specified dimensional and geometric requirements. These processes are crucial in manufacturing and quality control to verify that parts are produced within acceptable tolerances and adhere to design specifications.

Dimensional inspection and analysis play a critical role in ensuring the quality and consistency of manufactured components. By utilizing advanced measurement tools and techniques, Rotatek can help manufacturers identify and address deviations early in the production process, leading to improved product quality and adherence to design specifications.

Dimensional Inspection and Analysis Services
Part to CAD Inspection

Part to CAD inspection involves comparing the dimensions and geometry of a physical part to its corresponding Computer-Aided Design (CAD) model. This ensures that the manufactured part aligns with the intended design.

GD&T

GD&T (Geometric Dimensioning and Tolerancing) is a symbolic language used to communicate design specifications for parts and assemblies. It defines the allowable variations in form, orientation, location, and profile of features on a part.

Surface Mapping

Surface mapping involves creating a detailed map of a surface to identify irregularities, deformations and deviations from the desired specifications. This is important in applications where surface quality is critical, such as in aerospace, medical and industrial manufacturing.

First Article Inspection

First Article Inspection (FAI) is a comprehensive review and verification process performed on the first production run of a new part or assembly. It ensures that the manufacturing process is capable of producing parts that meet the specified requirements.

3D Measurements

Laser trackers operate by measuring two angles and a distance. The tracker sends a laser beam to a retroreflective target held against the object being measured. As light is reflected off the target, it bounced back and re-enters the tracker at the same position it left and is measured by a distance meter, measuring the distance between the tracker and target.

Distance Measurement

The tracker sends a laser beam to a retroreflective target held against the object to be measured. The reflectedbeam returns to the tracker and its precise distance is recorded.

3D Measurement

Two angle encoders measure the elevation and rotational angles while a highly accurate absolute distance meter is used to determine the 3D position of the target. This position is shown in the software as an X, Y, Z value.

Tracking

The target returns the reflected laser beam parallel but offset back to the tracker where it hits the position detector, which calculates the offset between the outgoing and incoming beam. Servo motors continuously (thousands of times per second) steer the tracker’s head to minimize the offset between the two beams, resulting in high-speed, dynamic measurements.
