Hello,
Could anyone give me a quick explanation of the edit feedrates dialog box in VR milling and also the cicle centre option in the offset page?
Thanks in advance! !

In VRMilling version 2:
Menu Editor -> Edit -> Modify Feedrates:
Check the top option to change all F values in the editor by a percentage (eg: F1000 will change to F2000 if you entered 200% in here)
Check the next option to Alter feedrates at B.
This means you enter a single feedrate value to change within the program, and alter ONLY that value by an amount (Shift+/-)
You also have some additional options to change all values above this value (B), below or at.
Offsets - Circle Centre Button
This option is useful for setting the workpiece offset for a round billet.
eg, if you have a chess piece in the milling machine, you may need some accurate way of finding the centre of it.
This circle centre button allows you to touch on 3 points around a round billet, and will find and set the centre to be X0 Y0. Once this has been set, it will make life easy when changing billet diameter, as nothing needs changing

Thanks for the reply(s),
How accurate do you have to be on the 3 points for circle centre?
Thanks.

I would put some tissue paper (Cig paper if you roll your own?) on the component and just jog the axes until the tissue paper is removed, do this 3 times. The idea is taken from a CMM (Corordinate Measuring Machine) but they have a fancy probe as opposed to a cutting tool. Its faster and easier than putting a DTI in the spindle and rotating its probe around the circumference of the component, might be less accurate but is depends on what you are manufacturing
