2D DYNAMIC ISLAND FACING

[manel]

HI

i want to cut in 2d dynamic high speed , i have an island in the pocket .How can I define the island geometrie

please how can i do selection of geometrie to  define the island

[Guest]

2 seperate toolpaths - ....unlike island pocketing there is no option for island pocketing

or......

If you have a solid, use a Dynamic Opti-Rough

look at this document , we can do island facing with 2D high speed, i dont know how to define the geometrie,

sorry i cant , thanx for your help , all i need to know is how to make island facing in 2D dynamic mill

in the pdf i shared , this can be done like pocket island facing

but i dont know how to select geometry so it can do the island facing

please help

Your pocket geometry should be at the bottom of the pocket.....define the island geometry at the depth that is the top of the island

where i can define the depth of the top of island, i dont find the function ,

If you post a file it would be easier for someone to help.

If the island is at the same height with the top of the part  you only need 2d geometry. I usually set Z zero at the top of the part.

In the Dynamic Mill toolpath, select as Machining region the pocket chain and as Avoidance region the island chain. (2018 - I do not know what version of Mastercam are you using)

In the Linking give the depth of the  pocket -1 (If the  pocket is 1" deep)

 

If the island top is below the top of the part you need to create the geometry used in the toolpath at the proper z depth.

In my next example, z zero is at the top of the part; the pocket depth is  at -1" and the top of the island is at  - .25  (both measured from Z zero).

Create the 2D geometry at z zero. 

Use Translate command to move the chains at the proper Z depth: 

    Select the pocket geometry (Hold down the shift key and select one of the pocket entities)

    In the panel, enable Move and enter in the z field -1.

     Repeat the step for the island chain and enter Z-.25.

In the Dynamic Mill toolpath, select as Machining region the pocket chain and as Avoidance region the island chain. (2018 - I do not know what version of Mastercam are you using)

If you want to face the island, in the Depth Cuts:

   enable Use Island depths

   enable Island facing and give an Overlap 25% or more.

In the Linking give the Depth incremental and 0.0.
