Most torch height controls require an axis on the CNC. The Sensor THC, integrated into many Hypertherm CNCs, is also
an axis on the CNC. The Sensor THC axis, or lifter axis, is called a Z axis. Its positive direction is always up (skyward) and
its negative direction is always down (earthward).
The X, Y, and Z axes are all linear axes. To perform angled cutting, the cutting system needs one or more rotational axes to
position the tool or torch on an angle. These axes are commonly known as A, B, and C axes. Many bevel heads provide
two axes of rotation that the CNC coordinates along with the X, Y, and Z motion to position the torch. In a standard
orientation, the A axis rotates about the X axis, the B axis rotates about the Y axis, and the C axis rotates about the Z axis.
