With the new step taken by TESA with the introduction of their TESA-SCAN product family for non-contact measurement, the need for developing TESA-VISIO like systems as a further contribution to quality control appears as the next logical step to the company. So to complement, extend and enhance this product line, TESA have engineered a new line of high precision machines, including the innovative TESA-VISIO 300 available today in three different models. Each model comes equipped with a 300 x 200 mm coordinate stage.
1 Manual video machine provided with TESA-VISTA ñ the software tool for the most varied applications. Made simple to use, this software is within the reach of any end-user.
2 Manual video machine delivered with PCDmis ñ the enterprise-wide metrology software. Using the Vision capability of this software, the machine provides users with a powerful tool for non-contact measurement in two and three coordinate directions.
3 Automatic CNC controlled video machine (DCC) equipped with DC servomotors. Running the PCDmis Vision software, this machine is one the most cost-effective currently available on the market. Since users are not limited to a single choice when deciding upon the software to use, this results in a number of benefits our customers do very much appreciate.
Manual machine versions
These two versions have a coordinate stage fitted with a quick release system in both axes X and Y. This system enables fast displacements for locating the geometric feature to be measured. Releasable wheel drives are used for quick motion in the Z-axis as well as fine setting of the focal length.
DCC machine version
On this version again, the coordinate stage along with the vertical axis are displaced by means of DC servomotors. Their speed is tightly controlled through the rotative encoders, especially when the joystick is used or high precision images are processed in the X-direction. This for example. A plain axis with linear drive allows the stage to be displaced mechanically. This system also acts as coupling clutch in case of collision. Vertical displacement is ensured by rack and pinion.
Each variant comes with a high-resolution colour camera. The manual base version with TESA-VISTA has a motorised zoom, without coaxial light. Another version with a telecentric objective (magnification 2x) is planned for specific metrology applications. Both PCDmis models, whether manual or in DCC version, also include a motorised zoom (magnifications 0,7x to 4,5x). A calibration routine is provided with the software for the zoom. This routine makes dimensional inspection possible throughout the full range with no effect on accuracy for the measurements taken within the viewing area. Being an integral part of all our machines, the laser pointer helps users locating the area they want to check.
