The current traditional drilling machines are usually unable to identify the different kind of material hardness during the drilling action. Therefore, the drills are easily abraded or damaged which may cause the increase of cost. Due to these problems and disadvantages of the drills, this paper designs an intelligent automatic drilling machine to improve the disadvantages of traditional fixed speed drilling machines. The purpose of this design is to avoid the collision of hard material and cause the drill collapse or breaking. On the contrary, when the material’s hardness is lower, such as plastic materials, it can become a high-speed execution. After the penetrating, it will retreat from the subject in low-speed rotation. While using high-speed in drilling, faster speed can avoid the high temperature of drilling the materials. The high temperature will lead to the problem of deformation of aperture or low accuracy. The system integrates a touch screen and a PLC controller to automatically select and judge the materials for the drilling machine. The experiment proves the design can actually improve the drilling efficiency and extend the usage of drills.
