Description

Vision Measuring Machine – HVM-MT SERIES

Vision Measuring Machine (VMM), also known as an Optical Coordinate Measuring Machine (OCMM) or Vision Measurement System, is a sophisticated metrology tool used for precise and non-contact measurement of various objects. It relies on optical and imaging technology to capture detailed information about the shape, size, and dimensions of an object. VMMs are commonly used in industries like manufacturing, quality control, research and development, and more.

Key Features :

  1. Camera or Imaging System: The core component of a VMM is the camera or imaging system. It captures high-resolution images of the object being measured. The camera can be monochrome or color, and it may have multiple lenses or sensors for capturing different views and angles.
  2. Illumination System: To ensure clear and accurate imaging, VMMs often incorporate various lighting techniques, including backlighting, coaxial lighting, and ring lighting. These lighting sources help eliminate shadows and provide consistent illumination for the object.
  3. Precision Stage: VMMs have a precision stage that can move in the X, Y, and Z axes with high accuracy and repeatability. The stage allows for the precise positioning of the object under the camera for measurement.
  4. Software: The software plays a crucial role in a VMM’s operation. It processes the captured images, identifies measurement points, and performs various measurements and analyses. The software often includes features for geometric dimensioning and tolerancing (GD&T), surface analysis, and 3D modeling.
  5. Calibration System: Regular calibration is essential to ensure accurate measurements. VMMs have built-in calibration routines or require periodic calibration using standard artifacts to maintain measurement accuracy.
  6. Object Fixturing: Depending on the object’s size and shape, a VMM may include fixturing or clamping mechanisms to hold the object securely during measurement.
  7. Measurement Tools: VMMs offer a variety of measurement tools, such as edge detection, point-to-point measurement, circle fitting, and more. These tools allow for precise dimensional measurements, including lengths, angles, radii, and distances.
  8. Data Reporting: VMMs generate detailed measurement reports, often in the form of tables, graphs, and 3D visualizations. These reports provide valuable information for quality control and documentation purposes.

Applications of Vision Measuring Machines:

  • Quality Control: VMMs are commonly used in manufacturing industries to ensure the accuracy and quality of manufactured parts and components.
  • Reverse Engineering: They are used to create 3D models of existing objects or components, which is essential for reverse engineering processes.
  • Research and Development: VMMs play a crucial role in research and development activities, allowing scientists and engineers to measure and analyze prototypes and experimental parts.
  • Aerospace and Automotive: These industries rely on VMMs for precise measurement of critical components, such as turbine blades, engine parts, and intricate mechanical assemblies.
  • Medical Device Manufacturing: VMMs are used to inspect and measure medical devices, ensuring they meet strict quality standards.
  • Electronics Manufacturing: In electronics, VMMs help inspect PCBs, connectors, and other components for accuracy and quality.

Software

SPC STATISTIC ANALYSIS SOFTWARE

Our all Vision Measurement Machines are equipped with SPC analysis software to allow customers to analyse the measurement results in order to find the error trend in the production flow and have a chance to find problems in the production process on time to make a correction. This will avoid serious errors and waste in each production stage. The SPC Statistic analysis software provides a series of chart patterns & methods for management, such as Xbar‐R, Xbar‐S, Xmed‐R, R‐Rm etc, as well as a number of diagram representation methods, for example, vertical, horizontal, 3‐dimension, connection diagram etc to improve quality
management considerably.

BASIC FUNCTION OF THE SOFTWARE

Basic geometry measurement: Point, line, circle, arc, ellipse, rectangle and curves. Powerful measurement: Automatically find the best boundary point, automatically measure and identify line, circle and arc, can select the point, line, circle, arcs and ellipse with frame, can collect point. manually through a mouse.

Combination measurement: Combine the point, line and circle and calculate the distance, angle and intersection point among points, lines and circles. Geometrical error measurement: Measure the parallelism, perpendicular, inclination, displacement, coaxiality and symmetry.

Coordinate system setting: Parallelly move, rotate and change the original coordinate or reset the coordinate system. Dimension annotation: It can mark the length, angle, radius and diameter on the drawing window conveniently just like using AUTOCAD software.

Inspection result output: The drawings and measuring results can be put out in the format of WORD, EXCEL, DXT.

Auto focusing function: It can produce a focusing indicating curve by adjusting Z axis and then judge optimum focus distance position so as to reduce focusing error from operator.
Enlarge small window function: It can partly enlarge the vision window through the small window on the lower right corner of software so as to accurately aim at the workpiece.

CAD window: Special CAD window has the same idea as three coordinates, which make customer vividly understand the test pieces.

SPC function: Data statistics report can be edited freely according to user’s measuring requirements. Teaching function: User only need to program the measuring path one time when measuring batch parts and set the number of measuring times to automatically complete the measurement.
