Thread Milling 5 axis

[TheePres]

Has any of you accomplished this operation?

Any tips on how to begin, would i use a construction plane normal to hole to create toolpath, then change tool plane to top and this would give me the required A and B moves?

[gcode]

Leave your WSC at Top (or whatever the rest of the set is set to)

Make a toolplane normal to the hole

and use the regular threadmill cycle.

The post should output a point to point

toolpath.. You should also check the "linerarize

helix" box and set the value to something

appropriate to the size of thread you are milling

Thanks GCode,

So by using this format i could transform any 2-d toolpath into a 5axis movement??

 

Its no different than working with a rotab then!!!

[gcode]

Yes..make sure the Z axis of the Normal

tool plane is pointing up towards the spindle

just like Top does.. the Z pointing down will give you some really wicked gcode if your post

doesn't have axis travel limits properly defined.

 

a note of caution...

put a point at the origin of your file..

after using geometry to define a toolplane

click the white arrow and pick the origin point.

99% of the time you should see nothing but zeros

when you click on the Named Planes page.

If a toolpane is showing a non zero origin

the posted code will most likely be very wrong.

This assumes that the origin of your WCS is 0,0,0
