Title: Nc laser machining method
Inventor: AKAHA TAKASHI
IPC: B23K26/00
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To enable laser machining without stopping and to reduce ununiform depth at the beginning and the end of writing by rewriting the same circle multiple times continuously by one access and roughly synchronizing this rewriting of the beginning and the end with the irradiation and the stop of a laser beam. SOLUTION: In drawing a circle through NC command by a laser beam on a workpiece placed on a table, a command G22 (G33) for rewriting continuously multiple times in clockwise (counterclockwise) rotation is set, for the purpose of so drawing the circle repeatedly without stopping, as an NC command by NC control. Concretely, the G22 (G33) command, circular center coordinates and repeating number of times are instructed, for example, through the command of G22, I10, J20 and L5, a circle is drawn for five rounds continuously clockwise around the XY table coordinates (10, 20). Since this G command enables the continuous tracing of an operating circle locus, the start/stop of the table is eliminated for each round even if the same position becomes the starting point and the ending point, so that a circle with a nearly uniform depth can be drawn.

Abstract: PURPOSE:To test whether or not an alarm device can operate normally under the severest condition by detecting that the voltage of a battery drops from a prescribed threshold voltage. CONSTITUTION:When a low-battery testing switch 8 is closed, a circuit which by-passes a stabilization circuit 3 through a resistance 7 is formed.

Therefore, a low-battery detection circuit 6 gives a low-battery detecting output to an alarm display circuit 5 and the circuit 5 issues a low-battery alarm. Simultaneously, an operation testing switch 9 is closed and the circuit 5 issues an abnormality alarm based on a false abnormality detecting output when the circuit 5 normally operates in a state where the battery voltage is dropped from the threshold voltage Vr, in order to receives a false abnormality detecting signal.
