Title:
AUTOMATIC CARVING APPARATUS
Document Type and Number:
Japanese Patent JPH02303900
Kind Code:
A
Abstract:

PURPOSE: To simply carve a profile in a medal like a photograph by mounting a shape measuring means measuring the profile of a person three-dimensionally and a three-dimensional cutting processing machine carving the profile in one surface of the medal on the basis of the measured data.

CONSTITUTION: When a center line 15 is positioned so as to coincide with the center of a face while the monitor 11 of a three-dimensional shape measuring means 1 is looked and a switch is turned ON, a profile is projected on the CCDs 14a, 14b of cameras 12a, 12b to store an image in a CPU 2. The angle αmm of the point Fmm of the actual face and the lattice point Pmm on the CCD 14a at the point Fmm and the angle βmm of the point Fmm and the lattice point Qmm on the CCD 14b are calculated and the thickness Zm of the face at the point Fmm is calculated. Subsequently, all of the points P11-Pnn on the CCDs 14a, 14b corresponding to the points F11-Fnn of the profile are calculated to calculate the thickness of the face and, in the same way, the width X and height Y of the face are also calculated to measure a three-dimensional shape. Next, the obtained dimensions are corrected to carve the profile in the surface of a medal 4 by a carving machine 3.
