AS I understand it regular toolpaths pass the center line of the cutter through
the center of rotation
roll die sets the edge of the cutter to pass through the center ine
Goto screen - shade settings and make the part translucent
then it will be easier to see the selection arrow
If you have a lot of parts create a screen shortcut to toggle translucent setting
Try
In the create menu
create curve constant parameter
slide the select arrow onto the surface in the hole - it will work with solid faces
There are two choices one will give a line along the surface
the other will create a geometry as a circle - now just analyze entity properties
These calculations should allow the X Y and Z offsets for using a ball endmill to cut uniform chamfers
The easiest way to do the Z offset is to offset surfaces nad put edge curves on
Program the toolpath to the center of the ball endmill
It should be possible to write a script to do these calculations automatically
Offset the geometry in the z direction using offset contour
Planes will have to be set parallel to each side to get offet to work
Then offset this geometry in the xy plane
Then program a 3d contour using cutter comp to center of ball end mill
The key is that the offset is not the cutter radius but the radius where the cutter
contacts the part
It is not too difficult to get this number graphically - see the attachment for details
I can e-mail you a sample part if you wish - I am not familiar with uploading the files to the web site
Lay it out flat - write a mill pocket toolpath - roll it around the dia.
If the sides of the tab must be parallel in the veritcal direction
then you might have to use roldie - which is a c-hook
Is there a tutorial on building machines?
What is the process for building a machine?
What files are used and where are they located?
I would like to get stared building a couple of machines but dont see how to go about it
Thanks for any info to help me get started
setting the part so the hole surface is in the top plane with 0 on the bottom of the part
Ball dia = .75
x 2.2813 y.9117
c -20.483 b -57.713
these are the posted values using 5 axis drill
parallel to a line through the center of the hole - origin set to tooling ball center
To cut the od try 3d contour this will leave
radii in the corners - for the chanfers
try swarf to finish the corners maybe
surface contours with lines for toolaxis control
some geometry needs to be created for this
I can e-mail you an example if you want
Toolpaths drill
select mask on arc
Select the hole size arc
Put window around all holes this size
Hit the enter key - this is what many forget
sort the pattern
green check mark
If your geometry is reasonably clean
after raster to vector conversion
Try opening up the chaining tolerannce and
writing contour toolpaths use tolpath filter
then save toolpaths as geometry
