This technology for high-density and high-speed measurement is expected to be applied to the field of reverse engineering such as detailed numerical design when designing models.

OPTON exhibited a high-speed Moire3D camera that captures shape data in a range at high speed and performs calculations to display measurement results in real time. The machine can measure shapes in the range of 50 × 50 ~ 1000 × 1000mm at a speed of 10000 coma / sec. For example, it can be used in the fields of vibration, displacement analysis or wavefront observation, online measurement, and the like.

Integration of measurement functions

Integration is also called compounding. It contains two aspects. One is to improve the function of the measuring machine and increase the testing items. On the other hand, it is to expand the detection range. One measuring machine is equipped with multiple detectors in different ways. Different measurement objects are detected separately. Measurements that used to be performed with multiple measuring machines in the past can now be done with a multi-function measuring machine, thus greatly improving the efficiency and measurement accuracy of the measuring work.

The German company Mahr exhibited a multi-function measuring machine at the meeting, which added the function of the coordinate measuring machine to the roundness measuring machine. As a roundness measuring machine, it is required to have a high-precision rotary axis and Z-axis drive mechanism, and then combine the long-stroke Y-axis and the X-axis drive mechanism with a rotary-type probe, so that the machine has coordinates. The function of the measuring machine. This measuring machine can measure geometric errors such as roundness, cylindricity and parallelism, as well as length and angle such as diameter and step. The measuring range of the machine is 300 (X) × 600 (Y) × 700 (Z) mm, the accuracy of measuring length U1 = 1.2+L / 500μm, U2 = 1.5 + L / 300μm, U3 = 2.0 + L / 300μm .

For a long time, the combination of a CMM and a rotary table can measure workpieces of complex shapes such as gears, crankshafts, and camshafts. Mahr's multi-function measuring machine makes it easy to measure long-sized large shaft shapes because it can effectively utilize the space on the rotary table. It is said that it can be further extended to measure complex cylindrical objects in the future.

A non-contact coordinate measuring machine equipped with a microscope, a CCD camera, and an image processing apparatus can be used for measuring the size and shape of a complicated small part such as a semiconductor, an electronic part, or a micro mold or a plastic product for molding. Some optical machines, measuring instruments, home appliances and other manufacturers in Japan have developed some unique testing products in the fields of positioning, focusing, lighting, edge detection, etc. In recent years, most products have been popularized and applied.

At this exhibition, four companies exhibited coordinate measuring machines with multiple sensors such as CCD sensors, laser sensors or contact probes. A total of three physical objects were exhibited. According to the sample, there are more than 10 models. Types of. For example, Japan's Mitutoyo exhibited a fast imaging image measuring machine. These types of contact probe sensors can measure three-dimensionally the size of intricate parts that are difficult to capture by the camera or any height dimension of deep holes. It can be seen that, in combination with the non-contact method using the optical principle, the coordinate measuring machine can be used in a wider application field.
