#CMT# #/CMT# The method involves receiving a selection of machining instruction (100), and considering a tool on the station (101) and checking availability of an equivalent tool at machining station. Transposition of origin of a piece to be machined is performed (104) by a space reference transposition module if the equivalent tool is available. Axial positions of the piece are transpositioned (105) according to the origin from the transposition. Machining instructions of the piece is translated (106) into equivalent machining instructions by machining data transposition module. #CMT# : #/CMT# Independent claims are also included for the following: (1) a device for preparing machining instructions for a numerical control machine tool (2) a data medium comprising a computer program comprising program code instructions for implementing a method for preparing machining instructions for a numerical control machine tool. #CMT#USE : #/CMT# Method for preparing machining instructions for a numerical control machine tool i.e. screw cutting machine (claimed). #CMT#ADVANTAGE : #/CMT# The method enables automatically transpositioning the machining operations from the main station toward recovery position and vice versa. The method enables comparing machining approaches of the piece or a series of the pieces without having to manually prepare all the possible combinations. The method enables reducing the time required for programming of machining sequence of the piece in returned position when the piece is placed on a machining plane in non-returned position. The method enables calculating and optimizing movements without time constraints of existing digital controls, and executing the precalculated movements without requiring real-time complicated calculations. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a functional flowchart illustrating steps of a method for preparing machining instructions for a numerical control machine tool. 100 : Step for receiving a selection of machining instruction to be transposed from a machining station to another machining station 101 : Step for considering a tool on level of machining station and checking availability of an equivalent tool at another station 104 : Step for performing transposition of origin 105 : Step for performing transposition of axial positions 106 : Step for transposition of machining data. |
