in a direction to reduce the error. The servo is a closedloop, or feedback system, because a signal applied to the controller causes rotation of the output shaft and thus changes the error angle with

tial contact of helical gear teeth is a point, which changes into a line as the teeth e into more engagement. In spur gears the line of contact is parallel to the axis of the rotation。 in helical

electronic transfer of information can save the analyst a significant amount of time in both steps 1 and 2. In addition , the mesh generation codes have also improved significantly in the last decade

conditions under which a spatially sinusoidal perturbation in the temperature and stress fields can grow exponentially with respect to the time in a similar manner to that adopted by Lee and Barber.

t low pressure to keep the flow resistance small,and once the cavity is filled, applies large clamping force on molds to form microstructures. Injection press molding has superb transforming
