Title:

METHOD OF SETTING BORING CONDITION

Document Type and Number:

WIPO Patent Application WO/1991/013721

Kind Code:

A1

Abstract:

A method of setting a boring condition by which the working condition for defining of boring in an automatic programming can be set easily. In this method, when one of various registered bore form definitions displayed is selected by an operator, it is asked whether change of a registered working condition corresponding to the selected definition is necessary or not (S1) and if unnecessary, the registered working condition is set as a set working condition (S2). When the changing is selected, first and second coefficients are read out from a look-up table according to the combination of a work material represented by manually inputted data and the kind of boring relative to the selected bore form definition and the size of the tool. A rotational speed of the main shaft is calculated on the basis of the first coefficient and the manually set cutting speed, and a feed speed is calculated on the basis of the calculated rotational speed and the second coefficient to set both the calculated rotation and feed speeds as the working condition (S3). After the set working condition is changed as required, inputting a bore position (S7, S8), the defining of the boring is completed.
