Laser cutting apparatus with means for measuring cutting groove width
First Claim
1. A laser cutting apparatus including a laser oscillator for generating a laser beam and a laser condenser lens for condensing said laser beam from said laser oscillator to make a cutting groove of predetermined width into an object being processed, said laser cutting apparatus comprising:
- means for adjusting distance between said object and said laser condenser lens for adjusting the width of said laser beam irradiating upon said object;
relative-speed regulating means for controlling the relative speed of said object with respect to said laser beam to regulate the irradiating time of said laser beam upon said object;
cutting-width measuring means for measuring of an upper portion and a lower portion of said cutting groove; and
controlling means for comparing the upper cutting width and the lower cutting width measured by said cutting-width measuring means, of said cutting groove with a standard dimension, and controlling said distance adjusting means and said relative-speed regulating means in accordance with the result of comparison.

Abstract
A laser cutting apparatus suitable for making a cutting groove into a die-manufacturing plywood used during production of package boxes includes a distance adjuster between an object being processed and a laser condenser lens for adjusting the width of a laser beam irradiating upon the object, a relative-speed regulator for controlling the relative speed of the object with respect to the laser beam to regulate the irradiating time of the laser beam upon the object, a cutting-width measuring unit for measuring the cutting widths of the upper portion and lower portion of the cutting groove, and a controller for comparing the measured cutting width of the cutting groove with a standard dimension and controlling the distance adjuster and relative-speed regulator in accordance with the result of the comparison.
