Fick cam to cam hemer
Instructions for producing programming cams and cam generation data for the most common makes of machine were included in engineering references well into the modern CNC era.
A cylindrical cam or barrel cam is a cam in which the follower rides on the surface of a cylinder.
In some applications, a single element, such as a gear, a barrel cam, or other rotating element with a flat face, may do duty as a face cam in addition to other purposes.
a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path.
Applications include machine tool drives, such as reciprocating saws, and shift control barrels in sequential transmissions, such as on most modern motorcycles.
A special case of this cam is constant lead, where the position of the follower is linear with rotation, as in a lead screw.
A simple displacement diagram illustrates the follower motion at a constant velocity rise followed by a similar return with a dwell in between as depicted in figure 2.
However, the most common type is in the valve actuators in internal combustion engines.A common example is the traditional sash window lock, where the cam is mounted to the top of the lower sash, and the follower is the hook on the upper sash.In this application, the cam is used to provide mechanical advantage in forcing the window shut, and also provides a self-locking action, like some worm gears, due to friction.Non-invertible functions, which require the groove to self-intersect, can be implemented using special follower designs.
