Hi forum.

Is there anyone who can help me?

I'm a beginner at milling metal, so bear with me if it doesn't look perfect. I think the milling bit is worn out, which is probably why there are a lot of burrs, but that's not the issue.

I've attached two pictures to this thread: one from Fusion360 showing the model I designed and exported to RoboDK, and another showing how it turns out in reality.

The Yaskawa DX200 MH50 robot I'm working with, where my program is run, is doing some strange things while milling. You can see this in the picture of the aluminum plate where I tried to mill my model. It's just a test model, but it should ideally look like the one in Fusion360.

For some reason, the robot skips the corners of the squares, making them rounded. What is wrong, and which setting should I change in RoboDK to prevent this from happening again?


Best regards
Stig

Did you calibrate the robot tool (TCP)? Did you change the tool orientation while milling?

Can you send us the Fusion model and the RoboDK project file?

We can take a better look.

Hi Albert.

I have send the project files to your info@robodk.com mail.

Sure, we'll take a deeper look.

Hi Albert and Lindberg87,

Can you provide some clarity on what the problem was and how it was fixed? We are evaluating the use of RoboDK for an robotic machining application and this kind of thing is concerning.

This issue was related to the rounding instruction, which was present at the beginning of the program.

To generate accurate programs and make accurate cuts (so to prevent this curve effect) it is better to set rounding to 0 (default value).
