Hybrid Finishing

[cunder]

I have read some postings of users have trouble with the Hybrid finishing. Are some of You using it sucsessfully? I have not tried it yet and was considering using on a one up mold. Thank for any comments.

it seems to work a bit better in MU1, but i still use the old style finishing,

I used it last week on a small 1-cav insert.......it worked well

Two tools, two paths. Opti-rough with a 1/2" w/.09 nr and hybrid finish with a 3/16" w.02 nr

Go ahead and practice with it, it's good for mold builders

I can get it to work, but its not all it was advertised as. You have to play with the angles. ai wish they would just give you a constant z option in the scallop toolpaths.

I have used it several times, all successful, in MU1.

I set the step down and step over the same and use 89° exclusively for a perfect constant scallop.

 

here is an example using it on a heat sink type cavity mold

.

Hope this helps

 

Its my favorite path and saves me from doing a rest waterline and then a finish waterline and then a finish scallop,

to (finish) irregular shaped contoured 3-d mold components

 

now I just do a rest waterline and then the hybrid

 

Cheers

Rest waterline? is this an X5 path? Are you just referring to waterline and leaving some stock for the hybrid path? BTW, that looks like a decent path from the pic.

Rest waterline? is this an X5 path?

 

Waterline has a rest option if you look at the branches, the Rest Material IS active

Motor, as John said check it out, it work quite well. There is no over lap so if I am

using a 1/4" ball and the last cutter was a 1/2" ball, then I punch in .540/.270 for the

rougher. (to get a bit of overlap)

I have better luck with 5x axis paths converted to 3 or 4 axis. may not be an option for you. All the HSS paths are a window select and cut. Not my style

BTW

 

I ran that path in the pic last night, it has a .004" step over using a 1/8 ball, it turned out polish free for our process.

[The Chipmaker]

Thanks Rick. I will try the 89'.

[Trevor Bailey]

i have had nothing but good performance from the hybrid path:

 

 

[Thee Rickster ™]

The hybrid path does not show progress in the multi threading manager,

does anybody else notice this?

Here is another one I just finished.

Could someone of you post a picture of finished surface made with hybrid finish? I curious to see what the surface finish looks like in a complex part. Also how much different is the machining time compared to scallop with same step over?

[Joe788]

Rickster, how long did it take to crunch that?

[Müřlıń®]

Ya I had people asking me how long the cycle time was

[Chris Rizzo]

Keep in mind, the settings in the enhanced filter will have a HUGE difference in surface finish. A great looking toolpath could look lousy on the part if the filter isn't dialed in, and vice versa.

Ok hybrid experts, check this one out.

This attached file has two exactly the same hybrid toolpaths in it. The only difference being one (operation #2) is being driven by the solid as selected in Mastercam in the graphics screen. The other toolpath (operation #1) is being driven by the exact same solid saved as an STL file.

 

For some strange reason the toolpath being driven by the solid inside of mastercam gouges where the toolpath (op1) being driven by the STL files looks great. What gives!

 

If you are going to check this file for your self you will need to save off your own copy of the solid model as an STL and drive operation 1 with it.

 

This also is not the first time I have run in to this where an external STL file gives much better results than selecting a solid inside of mastercam. This is a BIG problem the way I see it. BTW before you think it I will tell you this solid was built inside of mastercam.

 

Thanks,

Kevin, just curious, have you tried driving with surfaces instead of the solid?

[cobra95kev]

This is a very very strange issue. I just tried running no hist on the solid and it still gouges, It just gouges in slightly different areas???

Also to add insult to injury the op with the STL for drive surfaces regens about 3 or 4 times faster than the op with the solid tied to it.

 

Thanks guys,

Kevin C.

Joe,

No but I will try it real quick before knocking off for the night.

[cobra95kev]

No go on the surfaces. Gouges also.

[Thee Rickster ™]

Joe it only took about 5 minutes on my new P.C.

[Thee Rickster ™]

cobra kev, i wil not use solids ever, MC imo does not play well with them,

I also never use, make or convert stl's, i use surfaces (from solids) and only that

with all my moulds. Don't remember the last time I had a gouge.

 

customers that send me igs, also no problems

 

Sounds like you have a bad file from your customer

[cobra95kev]

rickster please read all of my posts. This is not a customers model it was created in mastercam. I also tried it with surfaces it still gouged.
