.... The maximum depth of cut for a single ECG wheel pass is usually considered to be about 2.5 mm (0.100 in.). In surface grinding, the area of the electrode gap varies with wheel diameter and depth of cut ( Fig. 5 ). Therefore, maximum current and material removal is achieved at the maximum depth of cut. Typical...

... for prepreg and wet-rerolled rovings are similar. Each includes a winding comb (or series of rollers) that is designed to collimate the several strands of roving into a single band width for delivery to the mandrel. Wet winding differs primarily in that the dry fiber roving passes from a creel (or tensioner...

The high electrical current of the lightning arc can cause remelting and rapid quenching of the metal alloy, resulting in changes in microstructure and properties. Composite conductivity, however, is not as homogeneous as in metals. In carbon-fiber-reinforced composites...

In general, threads of 12 or 14 per 25 mm (1 in.) and finer can be ground in one pass of a single-edge wheel unless the unwrapped thread length is much greater than normal. The unwrapped length is approximately equal to the pitch circumference multiplied by the total number of thread...

..., epoxy is preferred, since it has the least shrinkage during cure. Room temperature curing resins are often ideal; however, they frequently need to be cured at least 8 h at 20 °C (68 °F), as oven curing may increase shrinkage.
