I have a tool that is used to make a double chamfer where the tool is set and adjusted from the left side (R4). I adjusted the program to have an offset half width of tool, but It seems like the offset is opposite of what I think it should be. The picture shows a part where the Z of the groove is -.03, but with an offset my post says +.0375 when it should be -.0975. I would like to know if I did set it opposite of what it should be and if so what is the reasoning behind it? To me if seems like the coodinate system of the tool should be moved -.0675 in the negative direction.
