Forked Swivel Head - HEIDENHAIN TNC 426 PB/M Technical Manual

Forked swivel head

6 – 58
In this example, the mechanical offset of a forked swivel head is determined
with a dial indicator and a cylinder with a known diameter.
Temporary input values for the machine parameters:
n
MP7500 = %xxxx101
n
MP7510.0 = %000100
n
MP7510.1 = %000010
n
MP7510.2 = %001000
n
MP7510.3 = %000001
n
MP7510.4 = %000010
n
MP7510.5 = %100000
