raduis on the end of fins

[juniormachinist]

ok guys another question i have done the toolpath for inbetween the fins but it doesnt do the the radius on the end any ideas?

You will have to do a finishing pass around the fins.

Just create geometries from the fins and do a contour toolpath for each fins.

can you please explain in more detail?

[jeffrey001]

This is a solid, so just go to menu, create curves on all edges or create curves on one edge.

I think the best is to create curves on all edges on another level with another color.

Go to Toolpath, Contour, and select the edges you create.

Choose compensation left or right, for climb milling or conventional milling.

Just take care in which direction you choose the curves because this will deternine the cutting direction and if the tool go to the outside or the inside of the selected curves.

Hope this help. Jeff

i cant seem to find the thing to use
im using solidworks 2010 with mastercam x5 in built into the program

[jeffrey001]

It is in the menu:


Go to the menu: CREATE

Choose Create Curves

Choose Curves on all edges

Select the face with the fins.

If you selected another color for the geometry, you will see the geometry around each fins.

your using a different program then me

Junior,
Don't worry too much,

Canada is a long way away,,,,
SO YOU HAVE TO SPEAK LOUDER FOR HIM TO HEAR YOU....

There are a couple of ways to define items to generate toolpaths to.
- actual wireframe geometry
- select vertices (joints) between solid faces or surfaces

For a beginner, it may be best to be selecting wireframe geometry
-if you do not have lines and arcs etc, on the joints of your solid, you will have to create them

Not exactly sure of SOLIDWORKS ( Jeff, note the software ) icons or terminology. but you should be able to extract, or create, the entities from the solid.

You may have to be in the Solidworks drafting side to actually create these items, this is where I would be looking.
If you can get to "create items from solid", easiest is to create them on all edges,,,but you will have problems chaining a profile as it will have lots of "branch" point ( choice of chain path, you have to pick which direction to follow ).
It may be best to choose either by each single vertice, or by face. This would cut down on the number of branch points you would encounter

In Mastercam for Solidworks, edges in solids (including tangent ones) are already selectable curves so no need to create wireframe geometry from solid. Anybody here who's still unknown to Solidworks, please give it a try if you have the chance. You won't regret it. Although Mastercam for Solidworks is very limited in capability, Solidworks itself is one of the most powerfull & intuitive CAD out there.

Junior, try 2D Pocket with your 10mm tool. As gap between fins is 10 mm, tool will not enter them instead only make weavy moves at ends of the fins. Keep only Finishing moves, i.e., check off Roughing in Pocket.

what settings should i choose for the toolpath i.e turning stuff on or off
