Forward milling: the direction of the horizontal component FX of the cutting force F is the same as that of the feed direction F. this milling method
Reverse milling: the direction of the horizontal component FX of the cutting force F is opposite to that of the feed direction F. this milling method
Features of forward milling:
(1) It is easy to cause movement, so it is necessary to add a forward milling mechanism. (because of the gap between the lead screw and nut)
(2) The quality of machined surface is higher than that of reverse milling. (suitable for finish machining)
Characteristics of reverse milling:
(1) High working stability, no need for reverse milling mechanism
(2) The quality of machined surface is lower than that of forward milling (tool wear is fast)
