How do I prevent my tool from going into the workpiece during rapid motion (4-axis)?

[skalaiselvan]

Hello Community,

I am using 4 axis cnc mill with B axis as a rotational axis.

I used various offset surfaces for this program which you can see in the design tree.

I have spent considerable time in searching different forums and videos to find a solution to this problem.

I would like to show rather than explain in words. (sorry I had to hide the component name)

1. This is the work piece and the reference model as below.

2.For better understanding, this view will be used. You can see that sequence one is fine without gouging into the reference model.

3. So is the case with all the individual surface milling operations.

4. But when I run the tool path for the operation OP010 as whole, the tool passes through the model as shown 

Please suggest me how I can control these 'motions between the operations' without gouging into my workpiece.

thanks in advance.

Soorya,

Can you share the model? So I can have a look into it and can understand better.

Hope this helps.

I think he meant the manufacturing file not just the prt

It could be that this is only a visual illusion, thatt you see on screen, when you use 4-axis with a rotation table.

In reality the Postprocessor would apply a rotation of the table between sequences that start under different angles.

However, in Creo you see only a direct move from the last point of the previous sequence to the first point of the next sequence, which goes through the workpiece.

Check the CLDATA for rotate commands.
