SURFACE FINISH CONTOUR

[HEAVY METAL]

MY TOOLPATH IS BEING PLACED ON WRONG SIDE OF SURFACE.HOW DO I CHANGE SIDES.I AM MACHINEING A WALL THAT IS TAPERED FROM TOP TO BOTTOM

 

THANKS

[HEAVY METAL]

WHEN I USE EDGE SETTINGS THE TOOLPATH FORMS A BIG LOOP AROUND BOTH SIDES OF SURFACE

[cadcam]

you need to modify the Normal of the surface.

that should take care of that.

Hi HEAVY METAL,

 

- Normal of the surface not you problem. Mastercam toolpath not affected for normal surface .

- Check our Tool Plane (Tplane).

- For Flowline, check Offset in Flowline menu.

Good point Wallace.

jay is lacking latly.

On a surface contour you might need to create some tool center boundries (inside and out so you can stay inside a "donut" and not cut the other side of the surface). Or you could create a surface to fill the "hole" on the side of the surface that you don't want to machine and use that as a check surface. Surface contours will always get any part of the surface that it can and carry that contour down to the specified final depth of the program.HTH

HEAVY METAL,

 

Wallace is correct. You may also want to provide some sort of limiting boundary so your toolpath won't loop around the surface. Edge Settings alone usually doesn't wrap the toolpath completely around the surface. Surface Contour toolpaths tend to do all sides of the selected surfaces unless the tool can't physically machine it from that plane (i.e. bottom of part from Top Tplane), or there is a boundary to prevent the tool from machining the other side. That's just the way the Contour toolpath works. Draw a 2-D shape around the surface and use it as a Tool Center Boundary, or create a second surface and use it as a Check Surface. HTH

 

Jay,

What's up with that?!

[cadcam]

You know it just hit me before I read the rest of the post what he was doing.

Did not relize at first he was doing surface contour.

and it want to wrap around on a single surface.

 

Boundry boundry.come jay

 

I have not been all here latly.

I need to take the time like I used to.

 

Bad jay.

Mr metal are you using more then one surface?

What version are you using 8.1.1 or V9.

 

I just did a quick one in V9 with a 5.deg taperd surface and worked great n boundry.

 

But I know in the past I have had that trouble and have used a boundry to fix it.

 

The surface Normal was totaly WRONG.

i think you might need to put some check surfaces

or other surfaces that bascially say "don't go here", in there and maybe some boundaries.
