Inspection & Quality

In the world of high-precision metrology, all parts are elastic, which means they will deform to some extent under applied force, even if only by a few millionths of an inch. But certain parts, like thin-walled bearing rings, deform much more readily than others, to the point where it is extremely difficult for quality control technicians to obtain accurate measurements of their undeformed size. In other applications, such as precision balls and spheres, standards call for reporting size in an undeformed state, which frequently calls for a theoretical calculation. Now Mahr provides the capability to measure such parts in their undeformed state as a standard feature on their Precimar PLM 600-2 high precision length measuring systems.

As we climb out of the winter grind, we've all had our share of weighty issues to manage.

Hexagon Metrology has launched the Brown & Sharpe 4.5.4 SF, the latest generation of shop floor coordinate measuring machines (CMMs).

HEIDENHAIN's line of metrology digital readouts (DROs) has now received an upgrade. New LED screens are now being released on QUADRA-CHEKs (models ND 1100 and ND 1200) and the GAGE-CHEK model ND 2100, previously all with LCD screens.

Machine Technology column: A machine tool bed serves several important functions. It supports the machine's moving elements and supports them in geometric relation to each other. The relationship between the moving elements is more important than the relationship between the moving elements and the ground the machine is based on.
