CIRCLE 5 AXIS TOOLPATH and POCKET MILL CUTTING

Recommended Posts

IN MULTIAXIS TOOLPATH SELECTING THE OPTION CIRCLE 5 AXIS, PROCEEDING WITH ALL THE OPTIONS IT PROVIDES IN PARAMETERS IT DOSENT ALLOW YOU TO SELECT THE DIRECTION FOR THE TOOL TO CUT IN CLIMBING, IT JUST CUTS CONVENTIONAL. WHY?

OR

 

POCKET TOOLPATH WHEN YOU SELECT THE CHAINING TO PROCEED IN CLIMB CUT DIRECTION IT CUTS IN CONVINTIONAL, ENLESS YOU GO TO THE OPTION IN PARAMETERS "CUT PARAMETERS" SELECT CONVENTIONAL FOR THE MACHING DIRECTION. WHY?

First thing, turn the caps lock off. That is interpreted as yelling.

 

5 axis circle mill select the compensation direction. The way it is set it will climb cut. If you switch it to right it will conventional cut. 

 

2d pocket, if you want it to default to conventional mill you will need to change it in your default library. Your geometry selection is a boundary not for setting the cut direction.

With all "Chain Based" Toolpaths, the Chaining Direction does matter. With 2D Pocket, for the "roughing" the chain is just interpreted as a boundary, but for the "finish" pass, the direction does matter. These tool paths have a "start point" and "end point". In the case of a closed chain, these points are coincident.

 

When you select your Chain, Mastercam will display a chaining "Arrow" that shows you the direction of the chain. The movement is always from the start point towards the endpoint, but there is also a chaining "side".

 

When you look at a Chain in Mastercam, there will be two arrows. The "Direction" arrow is the larger arrow, and shows you the direction that the tool is going to move. Then there is a "compensation side" arrow, that points either Left or Right. This arrow is perpendicular to the Direction arrow.

 

This can be most easily seen if you have an existing Tool Path with a chain. Right click on the "Geometry" icon underneath the tool path, and choose "Chain Manager".

 

In the Chain Manager, Right-Click on an existing chain. There are several options in this menu, but the two options we are interested in are "Reverse Direction" and "Change Side".

 

Reverse Direction will change the direction of the chain arrow. That changes the direction your tool moves. You need to be careful if you use this command, because it will automatically flip the "side". After you have set the "Direction" you want to go, look at the "Side" arrow. If it isn't correct, you will need to Right-Click on the chain again, and choose "Change side".

 

The "Chain Side" setting will actually toggle the Left/Right setting inside the tool path itself. If you edit the Tool Path Parameters, and change the compensation from left to right, or vise versa, it will flip the chaining side arrow in the Chain Manager. These settings are linked together.

 

This can be especially confusing if you have a tool path that uses multiple chains.

Colin,

 

 First off thanks for the reply. I always have my chain arrow pointing clockwise which is climb cutting, I don't have a problem with basic tool paths dealing with 2d parts. but I just notice that with the tool paths Surface Rough, Surface Finish, Surface High Speed and Multi Axis even though you have the chain arrow pointing in a clockwise direction "climb cutting" it while have the tool path go in a counter clockwise cut "conventional cut". but all these tool paths do provide a option to select "conventional cut" which will then force the tool path to cut in a clockwise direction "climb cutting".

As colin originally mentioned the chained geometry is being recognized as an area, I honestly love not having to worry about my arrow direction, just set it on the cut parameters page and don't worry about the direction unless you are using finish passes for the pocket or if you are using a contour type path.

 

This is also the way you can expect 2d high speed area (which for most parts I find works better than the pocket path but that's my opinion) and also the 2d high speed dynamic, which can blow the old fashon pocket toolpath out of the water when used appropriately
