Strategy

[malo]

Hi

I am new on high speed tool path.

I saw and practice the 2D HST and i think it work very good but on 3D HST strategy i think 3D HST has very unnecessary motion on around the work piece,like below picture: for roughing

 

 

 

 

for finishing:

 

 

but in 3D surface strategy doesn't have unnecessary motion.

 

 

 

What do you think about unnecessary motion?Is that usual and necessary for 3D HST strategy?

How can i control unnecessary motion and toll path on 3D HST?

Thank you for your attention

Use a larger tool with bigger step-overs, try and eliminate the lead in / outs

 

Looks as if you are using a 8-10mm cutter with about a 50% stepover

 

I'd go back to a Rough Surface Contour with a large cutter and ramp while spiralling down

3d HST roughing toolpaths should be called hangover toolpaths. they require little or no thought to produce. simply window the model click generate and pass out.

Sometimes when I have a lot of unnecessary motion I'll adjust my cut angle and re-generate my tool path.

Hi

Thank you for your reply.

Please tell me does you use HST for this work piece?

or you use pocket surface toolpath for roughing strategy?

 

 

Thank you

Why is it that I dont see the 3D HST's in the list?

I would use pocket, outside in, plunge outside boundry.

Thanks John, that would be why...I dont have it! /cry

looks like one way cutting is turned on, but can you get away with zig-zagging it? with a roughing angle that's not liking the part
