Drilling is one of the basic, most frequently performed materials removing process in manufacturing industry. In spite of significant increase in the demand for economically producing holes, drill manufacturing is still considered as an esoteric art. The drilling operation is frequently used as a preliminary step for many operations like boring, reaming and tapping. Surface roughness plays an important role in product quality and manufacturing process planning. Twist drills are used in a diameter range from 1 to 20mm. Surface finish quality of work piece is an issue of main concern to the manufacturing industry and the inspection of surface roughness of the work piece is a very important technology. Drill wear has a bad effect on the surface finish and dimensional accuracy of the work piece. There still exists a lack of knowledge on the exact relationship between the point geometry, the grinding process parameters and the process machines, resulting in many methods for drill production and consequently wide variation in process performance. The variables selected for modeling of surface roughness are cutting speed, cutting feed, machining time and thrust force. The relative comparison of drilled surface produced by twist drills by different make (tool X and tool Y) is to be carried out by actual measurement, statistical analysis and inverse coefficient matrix method.
