Contour Spiral

[Thee Rickster ™]

X2 MR2 SP1

 

I have a .333 Ø hole 1/2" deep.

(Using a 1/4" em, contour path.)

 

Since a lead in would be really tiny, how do I tell it to spiral to depth?

 

thanks in advance

Use contour -ramp

In the pull down menu in your contour parameters.

I still prefer the contour ramp ol skool thats good to me. I think before X alot of people didnt realize it was there so they gave it a differant name and place. I use contour ramp for any closed chian just about no matter the shape. Constant tool engagement rocks. Just a late .02 thrown in.

I just used it to, contour ramp, a rectangular pocket.

 

that is now my new choice for profiling a contour

What exactly does wear function do?

Turns on tool comp.

Wear comp is offset in the computer which is more accurate,but also uses G41G42 to allow for tool wear or deflection in the control

I have never used a tool comp.

 

I went from cutting molds by hand to p.c. cad/cam. (using DNC)

I guess for production parts the wear factor allows the machinist to adjust it at the machine, because it puts the comp in the program.(?)

 

core pin and inserts pockets are all I do 2-d the rest is surface machining.

 

thanks for the tips

A little late to the game here...

 

i'd use circ mill with depth cut on and you'll get a nice spiral with all the proper leads etc.

How do you mill the pocket walls to finish size? That's where you can use wear comp.

Contour ramp is one of my favorite toolpaths.

Thad, I using contour 2-d. But my molds are a chunk of graphite. It not poco either. its sr-40 at carbone of America and EC-14 at MWI.

(as small as 8"x8"x2" and as big as 40" x 30" x12"

per mold half)

 

I replace cutters as soon as they look or feel dull.

 

I offset the pockets .002. i have a custom tool grind shop that makes all my sharp endmills with a +.0000/-.0003 tolerance on the dia.

 

We ruff the pockets to size with designated bull end mills and finish contour to size with the brand new shape ones. make for a perfect slip fit.

Sounds like you should be using Wear........I think you would like.........no need to offset your pockets.
