3d, 2d toolpath contour and pocketing

[drexen16]

i am trying to create a bowl with mastercam out of a piece of wood that is 5x5x2 (width x length x height). and i am having some trouble. i want to have 1/2 inch left on each side of the wood and the bottom. 1/2 flat endmill. i want the bowl to be straight down for the first half inch but then go down another inch. and then i need to pocket out all the area inside of that since a 1/2 in end mill cant go down 1 1/2 inch.

 

i am using:

mastercam x2

mill level 3

 

if you need any other info just ask.

Here is a model that meets your dims. The wall is vertical for the 1st 1/2 inch then curves inward to a fillet on the bottom. Now your 1/2 end mill can reach 1 1/2 deep without hitting the shank.

Why not just buy a long flute end mill?

[drexen16]

sorry, my description was a little off. i want it to be more like a bowl as that the bottom is round.

the reason i dont by a new end mill is because i am trying to use solids for my project in high school and a flat end mill is one of the requirements. thank you for the drawing but i dont know how to get the drawings off of your reply and i want to know how to do it so that i can learn how to use mastercamx2 better.

thanks

are you wanting to make a round bowl?

 

go into front view and create your geo for half of it, make sure it is a closed chain with the centre say at origin.

 

Then go to iso view and revolve your chain around the center line, using solids/revolve.

 

Let me know if you need more assisstance.

drexen, you already have the model made, but it is a matter of machining it? Or am I wrong?

[drexen16]

i do not have my model done. i am still trying to figure out how solids work and how to alter them.

[Thee Starry™]

Then Lee is leading you down the easiest path!

[Thee Starry™]

So you need something along these lines?

 

 

[Thee Starry™]

I did that by using Lee's method. Took about 1 minute total. BTW.

[drexen16]

actually that is almost exactly what i need except the dimensions might not be correct unless you used the ones i had above. also, i cant tell wether or not there is a half inch cylinder on the top because the side view doesnt show it. when i just read the instructions that lee used i didnt exactly understand them. When he says Geo does he mean just draw a side view using lines or using solids. if he means solids then i dont know how to do that because i dont know how to cut solids in half like that. also, i dont know how to use solids revolve. i am a beginner.

 

thanks for all your guys' help so far.

Draw a 3D wireframe of half your bowl (side view or front view)and revolve about the CL of your bowl to create your solid.

 

Have you looked at any examples for drawing solids?

 

 

Look at the help section examples for solids.

[drexen16]

i dont understand, when i say i am a beginner i mean it. i dont know how to draw wireframe let alone only half of it. i have no idea what revolve about the cl means.

[Thee Starry™]

That means Center Line

 

Yes, BTW it has the 1/2 cylinder before going into the bowl. But only on the Inside Diameter.

 

It is exactly to your dimensions.

 

Yes, Lee means to use lines and arcs to draw with. Then use CREATE-SOLID-REVOLVE. You pick the lines and arcs (geo) you want, then when prompted, pick the center line and the solid will make itself from there.

when i try to do that i get an error code 55 that says cannot dtermine swung geometry. i have tried googling it but cannot find anything.

[Dan@home]

Sounds like you need to learn geometry creation, construction & tool planes better, before you attempt solid modeling. Although using solids can be pretty easy.

[drexen16]

i know. but i need to make this now. so if you know how to fix that error that would be great.

[drexen16]

hey, thanks everyone who helped me. i have finally figured it out and successfully created my bowl. thanks alot starry69, midwest and lee.

Good to hear drexen.
