Structure model of the drilling system
The structure of a micro-drilling machine can be simplified as shown in Fig.1.In Fig.1,spindle A is supported by two identical isotropic bearings in radial direction;spindle A and drill clamp C–D is connected by shaft B;micro-drill E–F is fixed in the clamp D.Drill part with the screw slots is taken as uniform shaft F by equivalent of the bending stiffness.Structure dimensions and parameters of the model are shown in Table 1.The drilling process is considered in three cases[4]for analyzing:(a)a drill does not contact the workpiece;(b) a drill just contacts the workpiece;(c)a drill tip penetrates the workpiece.

There is a lot of luck in drilling for oil. The drill may just miss the oil although it is near; on the ather hand, it may strike oil at a fairly high level . When the drill goes down, it brings up soil. The samples of soil from various depths are examined for traces of oil. If they are disappointed at one place, the drillers go to another. Creat sums of money have been spent, for example in the deserts of Egypt, in “prospecting” for oil. Sometimes little is found. When we buy a few gallons of petrol for our cars, we pay not only the cost of the petrol, but also part of the cost of the search that is always going on.

Multiple-edged tools can also be used.Drilling uses a twin-edged fluted tool for holes with depths up to 5 to 10 times the drill diameter.Whether the drill tyrns or the workpiece rotates,relative motion between the cutting edge and the workpiece is the important tactor.In milling operations a rotary cutter with a number of cutting edges engages the workpiece,which moves slowly with respect to the cytter.Plane or contoured surfaces may be prodyced.Depending on the geometry of the cutter and the type of feed.Horizontal or vertical axes of rotation may be ysed,and the feed of the workpiece may be in any of the three coorkinate direcions.

The ancient Egyptian in Fig.1 is drilling a hole with a bow drill.This drawing is similar to many executed on the walls of tombs,and shows some other drawing characteristics which appeared in most civilisations at the appropriate time.The attributes of a human face are more simply displayed in profile view; the legs are also better drawn in side view because the bending of the legs appears in true form.The shape of the torso,on the other hand,is generally more recognisable from the front and this makes it easier to represent the two arms naturally.There are,of course,exceptions,but for these reasons most drawings of people in this stage are contrived so that the middle part of the figure is twisted-side view of head,front view of torso,and side view of legs.The other pictures in Fig.1 are from the Mosaic Standard fromUrand illustrate the same kind of technique as practised by the Babylonians about 2500 B.C.
