Need Help!- Swept 2d Contour

[mrsammy]

Guys,

I have to admit, that I never attended any sort of formal CNC Programming courses. I learned it totally by field experience. I'm currently using Mastercam 9 and Mpfan as my main post processor.

I do OK with simple contour like linear, pocket, slot and island. My only problem for the moment is dealing with swept 2d contour. I don't even know where to start. I really needed help on this and I hope every good people here could help me. I really appreciate it, if you guys could give me any advice on this.

If there any links available regarding this matter I really hope you guys could forward it to my email at davesarawak@gmail.com

I wish that I have reply on this soon. Sincerely from my heart, I thank you all.

Thanks dpark1 for your concern. Perhaps you can help me with above matter?

Anyway feel free to look at my file.

Thanks again.

is this the section you want to have swept?

i did this one in a ruled surface.

[timmydabull]

generally to create a swept surface you need to have 2 across chains-chains that are parrallel to each other and a along chain-a chain that intersects the across chains.

for some reason i am having a hard time using your geometry to create a swept surface (could very well be me as i am new to surfaces in general)

hope some of this is useful.

ps to create a ruled surface go to create-surface-ruled/lofted-select 2 chains going in the same direction and hit enter.

will be good enough to get smooth surface toolpath.

Swept2d, see if this helps.

i keep forgetting about 2d wireframe options,my mistake is i keep trying to use a surface option on a wireframe.

thank you.

Thanks a lot guys. You guys r all great. Thanks for all your reply, I appreciate it.

is it possible to have a roughing and finishing pass in the Swept 2D? i need to make a part that looks like a Half Pipe skateboard ramp. i can get it to go along the arc but i can't get it to rough it. the tool just wants to take it in one pass it looks like on the simulator. thanks for any input

Under run user apps you will find what in the picture.

i just got off the phone with mastercam and they said i can't do it with the level of software i have. i only have 2d capabilities. they said the swept 2d is only a finishing tool path. so i guess i'll either have to offset it or make a series of pockets to rough it out. if anyone has a better idea other than buying the next software package let me know. thanks
