smallest chip thickness which usually occurs at the end lacuna of different size in addition the chip thickness is affected both by the feed of the milling cutter in the x direction and by the speed of rotation of the workpiece in order to achieve an average chip thickness h mitt which is as uniform as possible and as a second optimization target to achieve the desired optimally high cutting speed which is primarily effected by the rotation of the milling cutter it is usually necessary during machining of the web side face for both the rotational speed of the workpiece and also the feed of the milling cutter in the x direction and also the rotational speed of the milling cutter to be constantly adjusted in the case of a web cutting tip as shown in fig1 a the extent of the tip in the radial direction of the body of the milling cutter is referred to as the length of the cutting tip the extent in the tangential direction of the disc like body of the tool is referred to as the width and the extent in the direction of the cutting bit closest to the axial direction is referred to as the thickness fig1 b shows in the same direction.
