L.S. Starrett Co. has introduced the HVR100-Flip, a large-field-of-vision (FOV) benchtop vision measurement system that is capable of a vertical or horizontal orientation, featuring a high-resolution digital video camera and minimal optical distortion for accurate FOV measurements from as high as 90 mm (3.65").
The horizontal or vertical orientation feature lends the unite to a variety of applications, from flat parts such as gaskets and seals, to turned and threaded workpieces. The system can easily change from vertical to horizontal and back within minutes, and it can be placed on most sturdy workbenches.
The system has a 24" LCD touchscreen monitor, a 348 × 165-mm (13.7" × 6.5") stationary top plate and 165-mm (6.5") optics travel with a motorized power drive for accommodating various part sizes. An LED ring light provides surface illumination, and an LED backlight offers transmitted illumination.
The main operator interface displays a live video image with software measurement tools and graphical digital reading of measurements. A partial image can be resized using pan, zoom and measurements by simply tapping a feature on the monitor screen. A wireless keyboard and pointing device are also provided for entering file names and targeting key functions. The MetLogix M3 software includes 2D geometric functions such as points, lines, circles, arcs, rectangles, distances, slots, angles and skew. The part design digital overlay simplifies part inspection.
The system offers enhanced measurement capability and increases throughput with automatic part recognition, in which the user places the part anywhere in the FOV without any fixturing, and the system recognizes and inspects the part in seconds. Additional features include a digital comparator-DXF overlay, profile fitting and thread measurement.
Virtually every machine tool builder lists, as part of a machine's specification, accuracy and repeatability figures. What's generally not given is the method used to arrive at the figures. Though these methods are defined in linear positioning standards, not all builders use the same standards.
Here are some of the tools and techniques for making sure machine tools stay at peak performance levels.
Different instruments (and different operators) are prone to different errors.
