Abstract: Aim to the difficult problem of the inclined hole machining, the vibration drilling method is analysed and adopted. The experiment of the 60°inclined hole drilling on high-temperature alloy was performed, and the notable effects were obtained. It can be draw from the results that the vibration drilling method break the limit of the jig for the inclined hole driling. The vibration drilling the inclined hole has became the new path.

Abstract: In modern manufacturing industry, there are a great deal of micro inclined holes, which is a difficult problem to machining. A novel micro inclined hole drilling method, step vibration drilling, is adopted. The experiments are carried that 45 degrees inclined hole is drilled into the 45 steel workpiece with Φ0.5mm carbide drill bit. The notable result was obtained with the method of step vibration drilling for drilling 45 degrees inclined holes on 45 steel, which break the restriction of drill jig. The new approach is put forward for micro inclined hole.

Abstract: There are many inclined holes in modern manufacturing industry. Due to the special machining state of drilling out, the drilling jigs and other auxiliary mechods can not been used. There is intermittent cutting for a long time during drilling out, and the axial force and torque are also impact force, which cause the drill to break. The experiments results showed that the axial force and torque were also been incresed, especially the later, which is the principal factor of the drill fracture. So it is the experimental foundation for further to control and protect the dill to break.
