Fundamental relationships of the parameters; penetration rate, bit weight, rotary speed, bit horsepowers, flow rate, and pressure were developed using eight full-scale, oilfield diamond drilling bits under laboratory-controlled conditions. One thousand five hundred data points, with all the parameters, were analyzed with 642 plots and 131 multiple-regression analyses. The hydraulic lift under the diamond bit has been accounted for in order to obtain relationships of mechanical bit weight with torque and penetration.

KDP (potassium di-hydrogen phosphate) crystal is used to fabricate important electro-optic parts. It is a typical hard-to-machine material because it is soft, brittle, and anisotropic. Parts made of KDP usually have extremely high requirements for machining quality. Reported machining methods so far for KDP crystal include single point diamond turning, grinding, magnetorheological finishing, and polishing. This paper presents an experimental investigation on diamond drilling of KDP. Data of several output parameters (including grinding force and torque, surface roughness, and edge chipping) were collected and analyzed. Ultrasonic vibration was superimposed to the rotation of the tool to study its effects.

Polycrystalline Diamond Compact

Rock cutting, drilling and durability tests were conducted in order to obtain data to design polycrystalline diamond compact (PDC) bits for geothermal well drilling. Both conventional and new PDC bits with different rake angles were tested. The rock cutting tests revealed that cutting forces were minimized at −10 deg rake angle independent of rock type. In drilling and durability tests, a bit with backrake and siderake angles of −10 or −15 deg showed better performance concerning the penetration rate and the cutter strength. The new PDC bit exhibited better performance as compared to the conventional one, especially in hard rock drilling. Furthermore, a new PDC core bit (98.4 mm o. d., 66 mm i. d.) with eight cutters could be successfully applied to granite drilling equally as well as a bit with twelve cutters.
