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

The left to right motion of the left back gauge.

The tilt of the back gauge creating an vertically shifting back stop used for oddly flanged work pieces.

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 vertical motion of the back gauges.

The front to back motion of the right back gauge independent of the left back gauge.

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 ability of the machine to regulate its tonnage up to its maximum tonnage. This is greater with modern hydraulic brakes which can control their tonnage very accurately.
