Open the catalog to page 1Improving Your Machine Tool Performance What is the performance of your machine tools? It is better to catch errors before they appear in parts by measuring both the volumetric positioning accuracy and the dynamic contouring accuracy. Volumetric positioning accuracy Using the laser vector technique (patent pending), 3 displacement errors, 6 straightness errors and 3 squareness errors can be determined in a few hours while conventional laser interferometers may takes a few days. Dynamic contouring accuracy Using the laser/ballbar (patent pending),contouring accuracy of various radii at high...

Open the catalog to page 5Volumetric Calibration and Compensation What are the volumetric positioning errors? (0,30,20) A linear displacement error is the positioning error in the same direction as the axis direction. The volumetric positioning error is the positioning error in a spatial direction not necessarily in the direction of the axis motion. Hence this error is a vector and its three components are the linear displacement error, the vertical straightness and horizontal straightness. Using conventional laser interferometer to measure these errors is very complex, time consuming, and costly. The key is how to...
Open the catalog to page 6What is the laser vector measurement technique (patent pending)? The key to the laser vector measurement technique is that the measurement direction or the laser beam direction is not parallel to the displacement direction. Hence, the measured displacement errors are sensitive to the errors both parallel and perpendicular to the direction of the linear axis. One way to implement this technique is to perform the sequential step diagonal measurement discussed below. What is the body diagonal measurement? The ASME B5.54 standard section 5.9.2 Volumetric Performance Using Diagonal Displacement...
Open the catalog to page 7Dynamic Circular Contouring Measurement Why check the contouring accuracy? For high quality and productivity machining, high speed machining operations or die and mold manufacturing, to achieve the high precision and super-finishes, static positioning accuracy is not enough. The acceptable contour will depend on the volumetric positioning accuracy and the dynamic contouring accuracy, the machine acceleration and deceleration rate, and the servo algorithem. The standard verification of machine contouring accuracy is the use of circular tests. However, traditional telescoping ballbar is...
Open the catalog to page 8What is a laser/ballbar? A laser/ballbar is designed for the non-contact circular contouring measurement (Patent pending). The hardware used for the test are an MCV-500 laser calibration system, an optical adapter, and a flat-mirror target with an adjustable mount, a PC interface card, and a notebook PC with Windows™ software. For a small radius or high feed rate circular test, high data rate is required. With a special PCMCIA interface card, a data rate up to 1000 data/sec can be achieved. The software for the data collection and data processing is a Windows based software. With a few...
Open the catalog to page 9The laser/ballbar uses a laser Doppler displacement meter for the measurement. Hence the accuracy is very high, typically 1 ppm and traceable to NIST. The telescoping ballbar uses a transducer for the measurement. Hence the accuracy is low, need periodical calibration and it is sensitive to temperature changes. Of course, two sets of measurements with two setups are needed for the laser/ballbar to generate the circular path as compare to telescoping ballbar, only one setup and one set of measurement is needed. A performance comparison is shown below. What are the major features and...
