Abstract: Switch means on the frame of a forging device senses when the ram and piston enter a first zone of a pneumatic cushion during retraction to initiate timing. If a predetermined time has expired before the ram leaves the first zone, the fluid inlet valve is opened. If not, switch means senses when the ram and piston enter a second zone to initiate a second timing. If a second predetermined time expires before the ram leaves the second zone, the fluid inlet valve is opened. If not, switch means senses when the ram and piston enter a third zone, and after a predetermined time the fluid inlet valve is opened. Thus, by sensing ram position and measuring time ram remains within each zone, the effective upward velocity (distance/time) is measured and adaptive controls applied.
