10.1 Thread
Thread parameters
To determine the thread parameters, the control uses the following
table.
Where:
F: Thread pitch is calculated from the diameter, depending on
the thread type, where an asterisk * is given
Further information: "Thread", Page 678
P: Thread depth
R: Thread width
A: Thread angle, left
W: Thread angle, right
Calculation formula: Kb = 0.26384 * F – 0.1 * # F
Thread backlash ac (depending on the Thread pitch):
Thread pitch <= 1 : ac = 0.15
Thread pitch <= 2 : ac = 0.25
Thread pitch <= 6 : ac = 0.5
Thread pitch <= 13 : ac = 1
