Ramp

[BrianP.]

Using X4

 

Doing a slot .675 dp. in SS cutting on center no comp. Want to ramp to a depth cut in say a 2 inch length then go around the part and repeat for 2 or 3 passes. If I use ramp and put in say .25 it ramps .25 in a single pass around on a continious ramp. Cant use depth cuts with ramp. Is there a way to ramp for a certain distance and then finish the cut.

Use a Lead in.

 

Set the line to "tangent", set the ramp height, ramp length, and the "enter/exit at midpoint in closed contours" check box.

 

Make sure the Arc radius is set to 0.0 (so there is no arc on the lead in move).

 

This will give you a centerline ramp move that ramps down to each depth cut level.

 

You can decide if you want an exit move or not. I'd recommend a small one so that the tool doesn't rapid up the wall.

 

You can also turn on the "keep tool down" option under depth cuts. When the tool completes a pass, it will feed over to the start of your plunge ramp, then start the ramp move.

 

HTH,

Colin at home now but I believe I tried all combination's of the lead in ramp. Set the height to .25 the length to 2.0 tangent and it still went straight to the bottom. But I will double check in the morning. Thanks

You know I'm talking about Lead In/Out, not the "Ramp" options in Ramp contour right?

 

You need to make sure your contour type is 2D, and you need to enable depth cuts. Also, make sure the top of stock, feed plane, retract plane, and depth are set correctly.

 

I tried a sample path real quick before I make my first post, so I'm 100% confident that this works. You just have something set incorrectly. Let us know how it goes...

 

HTH,

O.K. at work now. Yes, we are both on the same page. 2D contour, lead in lead out. Settings are:

 

Contour type 2D, comp off, lead in/out tangent, enter at mid point, length 2.0 , ramp height .25, depth cuts set to .25. Top of stock is -1.0 with cut depth to -1.675. Plunges straight to depth and then starts cut.

 

I can write the code by hand so its not really a problem. It's just when I want Mastercam to do something I get friggin stubborn and got to figure it out.

Sometimes the "enter at midpoint" will get ya

Also, try with the "gouge check" unchecked. I've had to do that a few times to get what I wanted.

gouge check can supress ramping motion..

both up and down. As that is not a valid function of "gouge check" , I turned it in as a bug very late in the beta cycle.

Bingo. I think that was about the only thing I did not try. Thanks guy's. Appreciate all the responses.
