DeMeet Video Measuring Machines
Optical measurements are performed using the camera system, optics and adjustable illumination. Due to the non-contact nature of the measurements there is no risk of product deformation. Optical measuring is very suitable for products with fine structures and contact sensitive products. Another advantage of optical measurements is that edge information can be defined directly with high density of measuring points. Within the field of view of the DeMeet a very high accuracy can be achieved. A combination of high quality telecentric optics and DeMeet Sony sensor camera is integrated for a clear image with an excellent contrast and a high resolution. In combination with the image processing functionality of the DeMeet, this results in highly accurate measurements. Telecentric optics are supplied as a standard to avoid perspective image distortion around the center of the field of view. The DeMeet is either equipped with Nikon, Leica-Design or Mitutoyo optics with a large working distance for a brilliant image with high contrast providing optimal edge detection. The lenses with various magnifications from 1x to 10x are available and can be exchanged during a measuring run, generating a range in display magnification from 40x to 400x.
Video sensor technology
The machine is supplied with a position offset standard and field of view setting standard, which is required for the field of view (optical) calibration. The glass accuracy standard can also be used as a training object. With the option “prepared for Combo” a Video machine can be upgraded on a later date to a multi-sensor measuring machine for combined video (optical) and touch probe (contact) measurements. For upgrading of a Combo prepared machine on a later date a Combo upgrade pack can be ordered.
DeMeet Design and Quality
The application of quality components made by Schut and by well-known, specialized manufacturers ensures excellent performance and high accurate measurements. With the new design of the DeMeet measuring machine series no concessions have been made to accuracy and reliability. The new visually screwless cover design provides a better protection in the production environment and is highlighted with nickel-plated aluminum details which can be personalized. The open design of the DeMeet allows for easy operation and loading of the machine from all sides. The accuracy of the DeMeet measuring machines is guaranteed by a CAA 3D correction model (Computer-Aided Accuracy, error compensation).
DeMeet Machine construction
The DeMeet 3D CNC coordinate measuring machines are designed with a proven fixed bridge construction and moveable measuring table for high accuracy and accessibility. The completely covered drive system and integrated damping make the DeMeet machines very suitable for inline measuring on the production floor. The construction is a granite base plate with accuracy grade according to DIN 876/00, placed on well positioned shock absorbing points and resting on a welded base frame (for the DeMeet-220 the base plate is flat grinded cast iron). The XYZ base structure for the THK precision preloaded caged ball linear guides is made from extremely tension relieved, flat grinded cast iron, as the basis for a mechanical accurate construction. The axis drive system consists of Faulhaber high torque DC servo motors, TFE coated Kerk lead screws and Renishaw TONIC optical linear encoders with low sub-divisional error. The measuring table is made of tension relieved, wear-resistant, nickel-plated steel, with a mounting hole pattern for product fixtures and a flat aligned glass plate. The video model consists of a DeMeet camera with a Sony sensor and a telecentric optical system. In addition to the optical system the Combo model is equipped with a Renishaw touch probe system.
Illumination
Illumination is essential for accurate measurements. The DeMeet is standard equipped with LED based illumination (backlight, coaxial light and segmented ring light). A ring light consisting of a 3 rings, 16 segments and 48 cells LED pattern, that can be controlled per individual ring, segment and cell, is standard supplied for optimal light configuration. The ring light can be set in intensity and angle to achieve the best contrast with clearly defined edges. The backlight is transmitted from below and is used to highlight the profile of the edges. Coaxial lighting can be used for illumination inside deep located structures. The LED based backlight and coaxial light can be adjusted in intensity. The configuration of the illumination is automatically controlled during a CNC measuring run. A coaxial laser pointer assists navigation during creation of a measuring program.
Approve for DeMeet MultiSensor Software Paket
Approve for DeMeet is a true multi-sensor software package, where the difference in sensor origin of the measuring input is limited to only the necessary. All the measuring results of video and touch probe can be displayed, reported, exported and used in constructs together, and are dynamically updated. The measuring results can also be displayed together in a 3D view. Approve for DeMeet is designed to be a user-friendly software package, but is flexible and very elaborate to measure many products.
PTB software evaluation
Evaluation software for coordinate measuring machines. The accuracy of the evaluation software was verified by comparing the results obtained from the software with reference results supplied by the PTB (Physikalisch-Technische Bundesanstalt, Braunschweig, Germany). The Approve for DeMeet software has been placed in the class of the smallest deviations. More about Approve for DeMeet MultiSensor SoftwareFixture systems for DeMeet
A secure positioning of the measurement object is crucial for an accurate measurement result and the clamping system can also be used for pallet measurements. DF Fixture system DF-System is a fixture system developed and produced by Schut and designed for constructing 3D product fixtures, particularly for optical measurements, and is fully compatible with the measuring table of the DeMeet measuring machines. Alufix Fixture system Alufix is a flexible fixture system made of high-tensile aluminum. Alufix is a uniquely designed modular fixture system to prepare a product-fixture in a short time and is easy to mount and specially suitable for fixtures for heavier measuring objects Specialized Fixture systems If products have to be measured on a pallet where a standard fixturing system does not offer a correct solution - for example due to the unusual shape or small dimensions of the product - then a customized system can be the solution.
