Engineers squares (machinists squares or try squares) are used to verify squareness and consist of a steel blade inserted into a heavier body at an angle of 90º. The body and blade are aligned against the object being checked. Usually a small notch is added to the inside corner of the square to prevent small particles gathering there and affecting the square’s reading.
The Standard BS 929 is the specification that defines the requirements of Engineers Squares that come in three grades of accuracy, AA, A and B in sizes from 50mm x 40mm up to 1000mm x 1000mm. The Standard requires that the angular variations in squareness across the length of the blade to be no greater than +/- (2 + 8L) microns where L is the length of the blade in meters.
Metrology equipment of any type should not be subjected to impact such as being dropped as they are easily damaged or become inaccurate.
METROLOGY EQUIPMENT APPLICATIONS
There are a wide range of different types of metrology equipment with a host of applications. Although such equipment is in most cases robust, users need to ensure their equipment remain in good working order and accurate.
METROLOGY EQUIPMENT CALIBRATION PROCEDURES
Metrology equipment items are first cleaned and then checked to ensure that they are not damaged. They are then examined for accuracy over the range of use in accordance with the specific Standard or to specific manufacturer’s requirements if stated.
CMS uses calibrated state-of-the-art master equipment to verify that metrology equipment is measuring within requirements and adjusted if required.
Metrology equipment items are returned to clients with a comprehensive calibration report within three working days of receipt.
