GROOVING METHOD BY THERMAL CUTTING MACHINE, OPENING WINDOW SETTING METHOD FOR GROOVING, OPENING WINDOW WORKING METHOD AND WORKING DATA PREPARATION METHOD

Document Type and Number:

Japanese Patent JPH09155539

Kind Code:

A

Abstract:

To provide the method capable of executing all necessary grooving at the same time as thermal cutting, setting an appropriate opening window for grooving and efficiently working the grooving window.

When grooving of a plate 4 is executed with inclining a nozzle 2, prior to grooving, by arranging an opening window 1, to which the nozzle 2 inclined to a groove line 3 to be grooved is not interfered, grooving is executed while moving the nozzle 2 in the opening window 1. When the set opening window is interfered with the plate, the groove line 3 and opening window 1 is corrected for removing the interference, further, when the opening windows are overlapped in plural pieces, piercing of other opening windows are eliminated, the nozzle is quickly traversed at over lapped parts.
