Thanks for the replies.
1. How do i check I have the correct MADA?
2. I have contacted the person who installed the robot and they said the correct load was used (35kg for spindle and attachment plate)
3. We had the robot mastering checked 2 weeks ago with the EMT tool and everything was fine
4. For the powermill spindle calibration I have 3 tungsten carbide spikes 12mm diameter and 75/100/300mm in length turned to a very pointy point.
5. No i do not believe this is an absolute accuracy robot
6. I guess with only a 35kg load it is underloaded?
I am aware that the robot won't be as accurate as a convential milling machine but I am seeing large steps between toolpaths machined at different orientations (parts machined with tool vertical and parts machined with tool horizontal)
SkyeFire, with regards to the TCP being calibrated in mainly one orientation showing larger accuracy deviations when cutting at other orientaions. Is this a common issue with robots are there any documents/best practise that go through the best positions do perform tool calibration to minimise this issue?
When setting up the spindle calibration for powermill nothing is saved to the controller (I do save the short spike as i use it to take measurements and get positions of some work pieces to use in powermill). I perform 3, 4point measurements on a short spike and then 3, 4 point measurements on a long spike. The XYZ figures are then added into powermill form that gives and average short TCP and average long TCP then the software automatically calculates the tool attachment point and vector which all tool lengths will then fall somewhere on. all TCPs are then held within the program that i post out of powermill.
