A CNC machine is programmed to redefine the corner tolerance as a function of the corner angle based on a recognition that corners having angles not equal to 90&deg; have effective corner tolerances that are equal to the corner tolerance specified by the operator divided by the sine of the corner angle. An increase in machining speed is achieved, because, at corner angles not equal to 90&deg;, the redefined corner tolerance is larger than the operator-specified corner tolerance and the CNC machine is permitted to machine the corner at an earlier time than conventional CNC machines. The CNC machine is also programmed to provide the operator with an interactive control of the parameters that control the speed and accuracy of machining. With this feature, the operator is able to observe the effects of changing the control parameters on the speed and accuracy of machining, and to customize the control parameters to a particular type of tool or application based on the observations.

A skateboard capable of being adjusted for different weights and different desired ride characteristics without changing the distance between the fore and aft wheels. The truck assembly is mounted on an angled leaf spring and the leaf spring is slideably engaged against a pad having shoulder guides. The pad mounts against the skateboard and the leaf spring is attached to the pad. In one embodiment, the pad contains slots and is movable in a fore and aft direction to change the spring constant of the leaf spring holding the truck. The leaf spring is fixedly positioned to the skateboard and the pad is free to move in a fore and aft direction as a result of the slots thereby allowing the rider to change the effect of the spring and hence the angle to obtain different ride characteristics.
