Best method, not sure ?

[rchipper]

This part was programmed using generic geometry placed around the solid-303ss material. It worked a year ago for the person that did it but I am told it turned out to be a very costly part, broken tools and extended cycle time. I was wondering if this part would lend itself to the dynamic milling cycles. Would one of you experts like to teach a rookie something new ? I have little experience using dynamic milling and surface machining but I see how powerful it can be. I don't know if this is the best way to approach this part, your opinions would be very helpful. I have not rotated the part to the next positions yet as I wanted to know if this will even work.

 

Your opinions are always appreciated,

Helps if you share the part you are talking about.

I'm sorry,

I thought I attached the part. I went through the motions. What am I doing wrong?

[rchipper]

I will try again 1st thing in the morning. Is there anything I need to know about attaching files that may spare everyone some wasted time?

[rchipper]

Ok,

Here we go. This is the part(s). Have I done the WCS rotation correctly? I know that there are more fixture positions that need to be implemented.

Well I plugged away at it for a bit and this is what I came up with so far. Instead of trying to blend the radii with corner rounding tools, would it be pos. to finish them and fillets with a surface finish cycle in each position? I tried but do not have enough understanding of how these work. Trail and error! Wahoo.

Hello,

I was able to put in a little more time on this project. What I can't figure out is how to get the surface finish contour to clean up the top of the part. I am leaning quite a bit doing this but am stuck. Would someone mind taking a look and point me in the right direction?

 

Starting MastercamU this weekend, looking forward to it!

 

Thanks everyone.

I don't have access to X7 but it sounds like your trying to cut shallow surfaces. If this is the case, Surface finish contour and Waterline behave the same way and are not suitable in these areas. These tool paths are based on step down and slice the model in Z steps to calculate the tool path so a shallow slope ends up having a wide step over. Best used with faces that are 30. to 90. deg. In a pinch you could change your step down then use depth limits to control the finish, using a deeper step down in a second tool path for the steeper faces. For horizontal faces, use HSM horizontal, SF Parallel, HSM raster or scallop. For shallow slopes or flat angular faces, use SF Parallel, HSM raster, HSM scallop, SF Flowline, SF Blend. Other options are available as well. Hard to advise without a picture though.

Here you go. used the options of shallow and flats. Now I would of not use that path to finish that detail.

I would of use Flowline and contour to finish faster.

 

Have a good day.

MCMC here is a picture of the part he is trying to cut.

Spending time at MCU will point you in the right direction.

 

Thanks Jay. " Now I would of not use that path to finish that detail." I never cared for the shallow and flats option either. In a get er done mode, it's fine but it does leave something to be desired.

Jay,

 

Had you made changes to the file you posted or was that for MotorCityMinion to view?

 

Thank you both for the input. I will practice using your suggested methods.

[Jayson Kramer]

yes I made changes to finish as you asked please review.

[rchipper]

OK Jay,

 

I see the changes. Thank you again!
