In many circumstances,
optical 3D measurement may replace tactile measurements made with mechanical
gauges or coordinate measuring devices. It is used to verify that the geometric
dimensions (size, form, and position) of components are correct. A light source
(transmitter) that provides a unique, predetermined light signal to the test
item and a receiving device (receiver) that captures the light signal are the
typical components of optical sensor systems for 3D measurement operations. The
item modifies the optical signal's amplitude, phase, polarization, or direction
in a known way, which is then utilized as a measured variable. Depending on the
measurement technique, the object's surface structure or 3D information can be
inferred by analyzing this change.
In the field of
mechanical engineering, 3D measuring technology facilitates and expedites every
stage of the injection molding, blow molding, and thermoforming processes: from
the design and manufacture of prototypes and tools to the first item inspection
reports, assembly analysis, and load testing. optical 3D coordinate measuring
device that, regardless of the object size, enables non-contact measurements of
the whole surface of tools, electrodes, prototypes, and injection-molded
components. This technology even swiftly and thoroughly catches complicated freeform
features, unlike tactile measurement procedures. Full-field surface
measurements provide targeted tool correction and a quicker first item
inspection, which cut down on production lead times. The whole assessment
procedure as well as the measurements may be automated for quality control that
goes hand in hand with production.
Mold dimensions and tolerances are measured during the
production process using optical measuring devices. Since they are a
non-contact measurement technique, the mold is not physically touched,
potentially reducing the risk of mold damage. Many characteristics on molds may
be measured with optical measuring equipment. Coordinate measuring machines
(CMMs), optical profilers, and three-dimensional scanners are some of the most
popular kinds of optical measurement systems utilized in the mold-making
industry. In general, mold makers can benefit greatly from the use of optical
measuring equipment. They can aid in lowering expenses, shortening inspection
times, enhancing quality control, and improving accuracy.
