Thread milling axial
This cycle mills a thread into an exisiting bore hole.
The tool is positioned to the “thread end point“ within the bore hole.
The tool then approaches with the “approach radius R,“ mills the
thread in a 360° revolution, advancing by the “thread pitch F“. The
cycle then retracts the tool and returns it to the start point.
Information on the cycle parameters:
C:
Spindle angle (C-axis position)
Z1: Start point thread– default: Start point Z
Z2: End point thread
I: Internal thread diameter
R: Approach radius – default: (I – cutter diameter)/2
F1: Thread pitch
J: Thread direction – default: 0
• J=0: Right
• J=1: Left
H: Cutting direction – default: 0
• H=0: Up-cut milling
• H=1: Down-cut milling
