Downmilling (climb milling). As can be seen in Fig. 12.3b, in downmilling the cutter rotation coincides with the direction of feed at the contact point between the tool and the workpiece.
Slim hole sidetracking and window milling technology is one of the effective ways to cut down the comprehensive drilling cost and improve oil production rate.
