mill/turn tip required

[Harry Morse]

Using mill/turn for the first time we only have c axis no Y and have to make oval shape flange on a part like an exhaust flange. Seems to make a lot of code around the flange shape and do not see setting for cutter comp on the c axis. Should we use this or use a polar cycle to do that then have less code. And have tagged for a c cycle but does not seem to use cycle. Any tips?

Using a polar cycle like a G112 will allow you to use G02/G03 moves where as non-polar cycle cutting may be all point to point moves.

 

Also take a look at your oval geometry, it may be splines that are outputting point to point moves. Try to use the edit/simplify command to turn the spline/oval in to arcs.

Many thanks for the response. We drew it as line arc geometry so its only a few entities but it is being output as point to point moves and thats how we saw so much code. Even though the cycle is turned on in the settings thats how it is being output maybe we haven't switched something else on.

Harry,

 

This is how I would approach a face contour (I am assuming it is a face contour).

 

Draw the contour from the right face G-view and Cplane.

 

In the operation manager right click in the white area, click on lathe toolpaths,c-axis, face contour. Chain your geometry, pick tool, set speeds and feeds, depths and such.

At the bottom of the toolpath parameter page check the box beside the rotary axis button the click onm the button. make sure rotation type is set on "C-axis". Go back to toolpath parameter page and click on misc value. Un-check the box in the lower left corner (auto set to post values) and set mill cycle G107 to "1". On the contour page I set compensation type to computer for my rough pass and to wear for the finish pass. This allows G41/G42 cutter compensation.

Play with the other fields (lead in/out, contour type, etc) to get the path you want.

 

Hope this helps.

Phil, I think that way only works on fishing reel parts

Ya, you would know, Doug.

 

Are you guys busy? We have yet to see any slow down in demand for our reels. This surprises me since boat motors burn a lot of fuel. Thank heavens for people walking the river banks and beaches casting for bite.

Phil, our sales are down on the low end Walmart stuff, but that has to do with Walmarts new seasonal policy. Our high end stuff is doing really well. We took best of show in the European Tackle show last month with our Fin-Nor Santiago trolling reel. We are having trouble keeping up with orders on our machined reels. Very busy. We have a lot of prototype projects going right now, 2010 should be a really good year full of new products.
