Hello,
Posted this in the Doosan forum, wondered if anyone here could help,

I need to mill a 5.5mm dia hole x 7.5mm deep in the face of a part.

Using Doosan fanuc Oi

The hole centre is 4mm from the centre of the part (X0)

Assuming a 4mm hole is already drilled.

I've had a go, would be grateful if you guys could have a look & let me know what you think:

It looks good, but I'm sure your W's should be negative, and your comment on the G41 line
needs to have one open and one closed parenthesis

Ok, thanks for your help
