Hello everybody!

I need a tip. We want to mill a trapezoidal thread Tr67x40 P20 at Dmu 50 eVolution.

I have a milling cutter from Horn. I have lead angle of ~1o.75degrees. I wanted to putt he detail in the middle of the table, set the B-axis at the lead angle and move in the Y-axis. Turn C-axis and cover in Z. The thread has to be 60mm deep. I’m not fit with G7.

What should I pay attention to?

Regards, Reiko

Hello Reiko!

You should better engage the tool with G8.

Example:

…
N101 T1 M6 (SF 3.5 VHM)
N102 S12000 M3
N103 G54
N104 G0 X0 Y0 Z50 B0 C0
N105 (Nut 1)
N106 G8 A5=25 L1=1 F5000
N107 G0 X-48.5 Y-45
N108 G0 Z-41.5
N109 G1 Y-37.25 F1250
N110 G1 Z5
N111 G0 Z100
N112 (Nut 2)
N113 G8 A5=-25 L1=1 F5000
N114 G0 X-48.5 Y10
N115 G0 Z-41.5
N116 G1 Y2.75 F1250
N117 G1 Z5
N118 G0 Z50
N119 G8
