Perpendicularity of a Cylinder

[E.F.Seabloom]

Does anyone know how to check the perpendicularity of a cylinder in only one axis, like the -X- axis or -Y- axis? I need to inform our machinist which direction to adjust his machine to have a bore placed perpendicular to the surface. When using PC-DMIS 3.6, it will only allow me to do an Average.
Can someone help? Thanks.

You could measure a circle at the top of the bore and another at the bottom of the bore. Report only the axis you need.

Exactly how I do it.

Also, report the size. This may be a good indication whether your tool is wandering (bell shapes: when there is a difference between the diameter on top and the diameter on the bottom).

change your workplane to both of the other axis and dimension the angle in 2D
