All machines consist of three fundamental areas the point of operation, the power transmission device and the operating controls. Even though not employing a clutch, direct drives match the operational characteristics of "part revolution clutches" because the driving power may be disengaged during the stroke of the press. Pinch points are found in many places throughout the workplace. Examine how the principles of DfAM upend many of the long-standing rules around manufacturability - allowing engineers and designers to place a parts function at the center of their design considerations.

The answer is to restrict access to these hazards. Guards are meant to isolate workers from a pinch point while safety devices can have a number of purposes, such as shutting down the machine once a hand or other body part breaches the danger area, withdrawing the operators hand from that area and requiring operators to use both hands on machine controls. Semiautomatic feeding means feeding wherein the material or part being processed is placed within or removed from the point of operation by an auxiliary means controlled by operator on each stroke of the press.
