A groove is a key component of the structure of end mills, drills, and other integrated cutting tools. Machining a groove is one of the most difficult, timeconsuming, and costly manufacturing process; therefore, for the sake of reduction of the machining cost and meeting the environmental regulations, the modeling of a machined groove with known wheel geometry and position is necessary for ...

The structure of the microdrill head is complex. The head is composed of four surfaces: two first flanks B 1 and B 2, which are at 15° to the end plane and two second flanks A 1 and A 2 which are at 30° to the end plane of the microdrill head (Fig. 2).This complex spatial structure is generated generally by two grinding wheels which are assembled in a tool carrier as a pair (Fig. 3).

The cutting edge in this Iscar end mill is designed to help split chips. The DOC can also be increased. For example, the machinist could run a process using a 5/8" () diameter, twoflute end mill on titanium 6AL4V at 130 sfm using full slotting and 1× the diameter DOC for productivity of in³/min. ( cm3/min.).

In the manufacturing of drills, the flute grinding process is much different than on end mills. The contact area is higher and the force/grit is much higher. There are two methods companies use to flute these tools. Method 1 utilizes straight faced wheels as this greatly reduces the amount of grinding wheel inventory used for many sized tools.

The grinding process principle of the mill end flank face is shown in the Fig. 15. The 0° grinding point on the end face I of the grinding wheel is used in the grinding process of the end flank face. The mill rotates in the negative direction of the W axis until the included angle with the axis equal to the end relief angle value α.
