I have just been cutting some pockets with the mill wizard, they were 14.4mm x 22mm. i was initially using a 6mm 4 flute end mill but the ramp down was making them look like a capital D. I was rushing so just changed to a 3mm 4 flute end mill. This rectified the shape but the pockets were undersize by about 1.5 mm. In order to get a pocket of the correct size I had to enter a tool of 1.5mm diameter into the wizard while actually using a 3mm, it was almost as though the wizard was calculating based on the radius rather than diameter.
Anyone else noticed this or is it just me?
