Claim 17:
18. A method of operating a linear-actuated press machine for forming a part, the press machine comprises a first motor, a second motor, a linear actuator having a male-female thread mechanism, a tool coupled to the linear actuator, and a belt system coupling the first motor, the second motor, and the male-female thread mechanism, the method comprising:
by use of the second motor and the belt system, advancing the tool toward the part in a low-force and high-linear-speed condition;
while advancing the tool in the low-force and high-linear-speed condition, partially or fully disengaging the first motor from rotational movement caused by the belt system;
by use of the first motor and the belt system, forming the part with the tool in a high-force and low-linear-speed condition; and
after the part has been formed by the tool, retracting the tool from the part by use of at least one of the first motor and the second motor.
