**5.2 Programming operations of semi-finishing**

Although there is not a standard definition of semi-finishing for this application, here it will be naming semi-finishing the milling operations that has for objective become constant the value of the stock of material to be milled after by the finishing operation.

For this reason, the regions with remaining material after roughing besides the theoretical stock should be machined. In general, the semi-finishing is an operation of "roughing" in 2 ½ axes, in specific regions and can be divided in two phases: a) operations for removal of the degrees and b) operations for relief of corners, as presented previously.
