Considering the geometry of the drill point, the chip area was calculated mathematically depending on the drill

point angle. The chip areas were calculated by crossing these two measured geometric dimensions.

Similarly, bifurcation

point angles are calculated over a 29 x 29 pixels window located around the bifurcation point as shown in Figure 8.

Results confirm study by Dornfeld, Kim, Dechow, Hewson, and Chen (1999), or rather, increase in

point angle causes a significant reduction in burr height and burr thickness in the drilling of nonferrous metals.

Since increment in drill

point angle enhances the contact area of drill bit lips which results increase in volume of material removal per revolution and shearing of material which ultimately increases the temperature (Basiagaet.al; 2011).Drill diameter is highlighted as significant factor for heat generation than cutting speed and feed rate, because increase in surface contact area permits more heat transfer(Pandey and Panda, 2014).

The "

point angle" cultivars were Gn0270, Roc22, Yz06-407, Fn38, and Lc03-1137, clockwisely.

It has a 150 deg

point angle and point geometry designed for the best positioning accuracy.

The geometrical relation between the field

point angle and the ray incidence angle can be derived from Figure 6 as

The effect of the observation

point angle on the peak values of the electromagnetic fields are considered as shown in Figure 9 using a ground reflection factor of 0.1.

The average orbit factors of satellite under [J.sub.2] absorb impetus, which occur in long-term excursion, include perigee breadth angle, rise point ofintersection equator longitude and aclinic close

point angle. The size of excursion item is relative to semilong axes, eccentricity rate, and orbit obliquity:

In addition, the effects of the channel angel and observation

point angle (between the vector from channel base to image of observation point on the ground and the image of lightning channel on the ground surface) on the electromagnetic field values are evaluated.

The undeformed chip width is equivalent to the length of the drill lip, which depends on the

point angle as well as the drill size.
