 * Don't chamfer the edges of the holes, as per the drawing. When you mill the pocket in the second operation you will end up with clean holes with no leftover pieces of material to remove.
 * There is a dimension tolerance of 39.8 +/- 0.1mm on the round boss. This should be easy to achieve with a normal finishing 2D Contour toolpath, but make sure you inspect this dimension before removing the part from the mill.
-* There is a dimension tolerance of 38.0 +0.2 -0.0mm on the round pocket. This hole cannot be smaller than 38mm, but can be up to 0.2mm larger. Make sure you inspect this dimension before removing the part from the mill.

 * For the second operation you should make sure the origin is set in the correct place. The model box point origin may not reflect the surface that is actually sitting on the parallels. In the design workspace you can create a sketch on the correct plane (the base of the round boss) before projecting geometry and adding a point sketch geometry that can be used as the origin for the second operation.
