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.
measured from contact point to contact point (mesiodistal width of maxillary central incisors (R & L) 8.70+0.53 & 8.71+0.53 respectively, maxillary lateral incisors (R & L) 7.00+0.62 & 7.04+0.66 respectively and maxillary anine (R & L) 7.84+0.51 & 7.82+0.51) and measured from mesio-labio-incisal point angle
to disto-labio-incisal point angle
(mesiodistal width of maxillary central incisors (R & L) 8.10+0.52 and 8.10+0.53 respectively, maxillary lateral incisors (R & L) 6.46+0.61 & 6.53+0.62 respectively and maxillary canine (R & L) 6.97+0.48 & 6.95+0.52) respectively was established as an aid for appropriate diagnosis and treatment out come in different domains of dentistry.
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.
