    4 Axis Curve Toolpath

    Well these is a chook called roll die that might be what you're really after here. I looked at the parent solid and see your trying to accomplish what is referred to as a roll die shape. What that means is a roller needs to roll around that shape that is fixed to a point. It can spin around a fixed point, but the idea is keeping the of the roller bearing in contact with the surface of contact. John Summers developed this 25-30 years ago I believe to support this type of output where you really needed Y to change to machine the shape on a 4 Axis with the 4 Axis runnign along the X axis. I think swarf will get you there, but if not then might try out the Chook and see. Sorry I don't have any documentation on the toolpath and been a good 15 years since I needed to use it.

    cutting axle spline 2018

    Yes thanks I will try that as right now top of stock is set to .75 and I did have keep tool down checked and my material I want to remove I had to do a stock to leave -.05 Is there any other methods I should try thanks so much for the help . That is the exact type of tool I'm looking for thanks so much

    4 Axis Curve Toolpath

    See there I learned something new. I will give the swarf as try. I that doesn't do it I guess I will be cleaning up the curve lines. Thank you for your input.

    I see this with Catia models all the time. I've grown to hate Catia and I don't even use it.

    For Developers

    This would probably get more traction on the official forum. I would like to be able to select geo by level myself. I think this is a good idea. Then you can move any needed geo to that level and have all associated toolpaths regen.

    I'm very interested in your feedback on how you're running these and how they perform. I've tried a few and in my experience they chatter really bad. The extensions/gage line I've needed they seemed to have too much tool pressure. They were faster but they also chattered where a ball mill did not. Any way, please report back.

    AXIS Substitution problems...

    I would try changing the direction of the rotary from CCW to CW or vice versa, my guess is your rotary direction for Clockwise/Counter clockwise is Bass Ackwards
  10. I've gotten pretty proficient at applying the morph path. If you can post up a sample I'd be glad to give it a go.

    4 Axis Curve Toolpath

    The 5 Axis curve lines are not normal to the axis. I would use swarf like you are and give it a try. You can try curve, but the lines must be normal to the Axis of rotation not kicked over like they are. That would be something a 5 axis would want not a 4 axis.

    You could use Canned Text instead of Misc. Int./Misc. Reals as well. I think it's a cleaner method.

    AXIS Substitution problems...

    It all worked out for me, except for one odd issue. On the computer it was climb milling, on the machine it was conventional. Any ideas why that would be?

    You'll also need to set in the Options Advanced Settings the "Post Insert Custom GCode As Comment" as unchecked. By default it is checked.

    4 Axis Curve Toolpath

    That's an understatement. With swarf and 5 axis anything can happen.

    Right angle head spindle direction

    For a Fixed Angle RAH ( tool is mounted at one "orientation" or "Station" as Mastercam calls it), you only really need two offsets. The H Offset and the D offset. The D Offset is called with G45/G46, and the H is still called with G43. You would either program on the G18 or G19 plane. This allows you to still use G41/G42 with a separate D Offset, for circular or contour motion on that plane. That way you can accommodate a range of different RAH Tools, just by using Offset Registers on the machine.

    4 Axis Curve Toolpath

    Thanks crazy^millman, I reattached the file. Hopefully it works now. I have not tried the Swarf toolpath yet.

    Agree hard begin 4000 miles way from the problem to know exactly what is thew right answer.

    4 Axis Curve Toolpath

    5 axis Curve must be driven correctly to respect the walls. I tried downloading the file, but not working. Swarf is using the walls to define the cut and it works differently. With surface you may need to define enough vectors that align with the walls to get it to respect the walls. Have you tired posting and running the swarf toolpath? Just because it looks clean doesn't make it clean.

    Right angle head spindle direction

    You program for the tip of the tool 99% of the time in Mastercam and let the post do the work. On the DMU 80 since it was in all reality a 6 axis toolpath I had to cheat to get good code so if each tool had changed in length then I would had to make planes for that changes, but since I thought far enough ahead and made 3 tools needed all the same length then one plane worked for all 3 tools. I did one years ago where we had 14 different tools all ranging rom 6" to 16" in length in a RAH. They were all programmed for the 2 planes they were cutting. No different than 3+2 programming and the Tool Length was accounted for in the post and done. Each RAH presents it own challenges and like I said in this topic get a good post and don't fight more than you need to get good code.

    They used to have a "ram saver" icon. What happened to that?

    4 Axis Curve Toolpath

    Hi, I have been trying to figure out how to get the 4 axis Curve toolpath to respect the walls of the slot I need to cut. I will be using an Hass Mini Mill with a Haas HA5c rotary 4th axis. I first used the swarf toolpath and it looks pretty good but there is no option for Compensation. I would like to have control over stock to leave. Only making 2 prototypes for now. I am trying the Curve toolpath because I see it offers, Compensation Type. I will be honest, I have very limited experience with Multi axis toolpaths. That is why I am reaching out to those with more knowledge for some guidance. Could it be that the slot requires a 5 axis toolpath? I do see that some areas on the walls are not planar to the axis for 4 axis toolpaths. But then again why does the Swarf path look so clean? Anyhow, I have attached a file in hopes that someone will be able to point me in the right direction. 4th Axis_2 7-13-20.mcam

    Right angle head spindle direction

    What you will do if you get a different angle head with a different length, or if your tool tip distance to spindle center will change?
