The vertical motion of the moving beam. This does not mean the motion of the back gauge.

The left to right motion of the back gauges. This is used when bending with multiple setups down the press brake, allowing the gauges to move with the operator as he moves the work piece from one setu [..]

The tilt of the back gauge creating an angled bend line in relation to the back of the work piece.

The front to back motion of the back gauge.  The X Axis controls the flange length, positive motion moves the back gauge towards the operator and results in a smaller flange.

The depth of the press brake before the vertical supports limit flange length.  Most press brakes are only constrained by the throat of a brake around the driving cylinders.

Two or more press brakes controlled by the same controller which are used to bend extremely large parts.

The moment the punch touches and begins to apply tonnage to the work piece.  At this point the back gauge may retract to allow the work piece to form upwards freely.

A press brake which relies on a flywheel and clutch mechanism to mechanically transfer energy to cycle the ram.  Found on older machines this type of brake suffers from uneven tonnage application and [..]

The overall working length of the Brake Press beams from left to right.

A press brake which is driven through the high pressure transfer of a fluid into a cylinder.  Hydraulic press brakes can be very accurate and well controlled, so they are the dominant form of computer [..]
