Claim:
Method of producing holes of various dimensions and configurations in a workpiece using a portable orbital drilling machine, said workpiece having attached thereto a template with preformed guide holes located in a pattern corresponding to the positions of the holes to be formed in the workpiece, comprising: a) providing each guide hole with a readable information carrier containing an identification of the respective guide hole; b) identifying, when fixating the orbital drilling machine in a guide hole of the template, in which guide hole the drilling machine has been fixated by detecting the respective information carrier; c) transmitting the detected guide hole identification information to a hole database containing relevant process and dimensional parameters of the hole to be formed in the workpiece by the drilling machine fixated in that guide hole; d) instructing, by means of a control unit communicating with the hole database, the drilling machine to perform in the workpiece a hole-cutting process relevant to the identified position of the drilling machine; and e) successively repeating the above-mentioned steps b)-d) to complete the forming of all holes.
