how to set the plunge direction?

[VVV]

plunge angle

xy angle

plunge length

 

are there someone to tell me how to set these parameter in surface parallel. just why i need to set these parameter in some situation.

 

thank you.

This feature is mainly used to give the user more control over entry/exit. This setting is only applied to the first and last move of the cut. Here's a 45 degree plunge angle with a 0 degree xy and a .5 plunge length:

 

 

and here's the same thing with the XY angle set to 45 degrees:

 

 

Hope this helps!

I was un-aware of that feature! You the man Doug!

[VVV]

could you tell me how to get the toolpath picture? it is too useful.

 

another, you don't understand what i means. i want to know what time to set what size of angle.

[Slepydremr]

Setting the angle depends on couple things.

 

material:

 

For steel I go with a smoother angle than aluminum.

 

Clearance:

are there walls I don't want to violate.

 

and

The angle of the surface to your current toolplane also makes a difference.

 

 

There may be other factors at play here also it just depends on your situation.

 

If you put an example of what you're trying to do on the FTP I'm sure someone would take a look at it and make some suggestions for you.

could you give me a example?

The idea of Direction in surface paths is a better way of getting the tool into the surface cut without directly plunging with the center of the tool into the cut.

This also a good tool when doing surface under cutting with a Keyway cutter or lollypop tool.

Great tool for surfacing use it all the time.

I uasly try to make the tool come in so it uses a radial cut compared to say the direct axial cut. This the tool for that.

[VVV]

I want to know the angle relation between the tool and the workpiece.

 

just how to set the degree of angle in some situation.

[cadcam]

Does this help:

[VVV]

ha, I of course know where to set these parameter. what i don't know is how to set the angle degree in according to the shape of workpieces. thank you.

[cadcam]

Well if I catch you right each shape is different and there are NO rules for this. I would say most people do not use it because they don't know how to use it or how it works.

 

But like I say there is No golden rule, just how do you want to get the tool in and out most efficiently trying to avoid plunging or hitting another surface or so on.

 

If you have some thing pacific you are trying this on that you can share. I can try and help you with that one.

Jay,

 

I used to use this on Pencil cuts all the time. It's a great way to ramp into the part...until it quit working in MCX, that is. This still doesn't work, IIRC.
