Sometimes the projected geometry is not
clean enough to write a toolpath on
- create the geometry flat write a contour
toolpath and roll it around the dia.
in top view create 2 vertical lines x times
the number of cuts needed ie: 10 cuts would
require lines to be 10 x p1 x dia in length
they need to be located at both ends of the desired cut - then draw a line from the beginning of one line to the end of the other line - create a contour toolpath on this line
and use axis subtitution to create the code
This is also a way to create grease grooves
Also ran it by creating new splines on the
upper and lower edge of the vertical surface
and created a multiaxis swarf toolpath
limited to 4th axis - needed new splines because
the endpoints on the originals do not match
It will run 4 axis 3d contour if the spline is
broken into segments - part of the smaller
spline is undercut from the larger spline
and the walls are not perpendicular to the
axis of rotation so the part would not be
as drawn - maybe a 5 axis part?
If it is a 3d contour use xform offset contour in
the Z direction and program the tool to the
center not tip - draw a 3d contour in z and
write a toolpath using tip then backplot
using the front or side view this will
illustrate the problem
Create a series of concentric circles above the part create contour toolpaths on thes circles
- they are easy to select using window - then
use toopath project to project the cuts onto the surface
How about Create a drill toolpath using the
points and a ball endmill - create an stl
file of your surface - verify the toolpath
using the stl and save the result
I think this was discussed before but searched
and didnt find it - is there a way to have
trochoidal tool burial set so that it does not
do that loop motion on the ouside boundry?
Thanks for any help
From geometry opposite inerior angles are equal
when striaght lines intersect - so the tringles
formed are proportional - so let a be the long
unknown and b be the short unknown
5a - 6b = 0
a + b = 6
5a - 6b = 0
6a + 6b = 36 Mulitply by 6 and add
--------------
11a = 36 a = 3.2727 b= 2.7272
Even with art - photos are very difficult to get
good output - it doesn't handle colors or
grey scales well - good line art or clean
black and white photos are much better
Or create geometry above the part and project
the geometry down on the surface and use
contour 3d toolpaths - be aware that in order for
the contours to be accurate you need to offset
the contours in Z be the ball tool radius and
program to the center of the tool
If it is a solid and you dont have solids in
mastercam you can,t move the solid - if that
is the case create surfaces and then manipulate
the part or create a new WCS to suit
Two things to try set - point generator to create
more cut moves in the corner - enable fanning
which starts the tool leading into the corner before the corner actually starts
