Hi

I run a 4 axis mill wich the fourth axis is an A axis- revolving around the x axis. I want to use the drill and roughing sequences but do not succeed. In some of te sequences i can choose either 3,4 or 5 axis. but not the ones i've mentioned above. Is there anyone who have experience with these? There must be a way to make holes in a part using 4 axis. Look at attached picture for an example to solve

Matt,

I got it working!!! The reason why it wasn't working properly was that, the tool compensation was set to tool edge instead tool center. Thanks a lot man. Its all about the details.......

You have to have the workcell as 5 axis and use process manager. That will give you the option to create a drill 5 axis drill sequence, there is no 4 axis drill sequence.

Hello,

From the looks of your picture all you need is indexing to bore the holes in. All you have to do is create a cys at each hole then when you create your nc sequence pick the correct cys for the hole you want to machine. This will point the tool vector in a different angle and you will get a A axis output in your code. When I set a 4axis or indexing job up I usually work from the center of my part. I create a main cys then just rotate multiple cys at what ever angles I will be machining at. Then when you start creating your nc sequences you already are set up just pick the cys you want and retract distance for your tool. In your operation set up you can create a clear distance for rotary clearance. You will also need to make sure your post is set up for this. I f you need anymore help just let me know I will be glad to help you get going on your project.

Hello Matt,

Just a question. Do you have experience with milling on the 4th axis? Drilling holes is no problem for me, i use a simular option that you mentioned. I spent so many hours on cutting a segment out of a revolve. The 4-th axis is also an A axis revolving arround the X-axis. The only thing that worked a bit was a trajectory milling, but it is not done perfectly. Tommorow i will start a new project where this also needs an 60 degree of pie material out of a revolve. I will program this in Creo 2.0 Maybe Ptc simplified it.

Kind regards,

Paul

Hey Paul,

I do a lot of work with 4 axis machining I am assuming you are doing this on a vertical machining center. If so could you post a image of the shape so I could take a look at it? I would be glad to give you any tips I can to help you out.
