Optodyne Inc., Rancho Dominguez, Calif., a maker of laser measurement, calibration and compensation systems, recently introduced a new and improved laser calibration system—the MCV-500H and MCV-5000H.
The MCV-500H and MCV-5000H laser calibration system is a basic system for linear displacement measurement, the company said in a news release issued Dec. 17, 2015. The system also works with accessories such as the SD-500 to perform 3D volumetric position error measurement, the AM-500 for angular error measurement, the LB-500 for dynamic circular contouring measurement, and the SP-500 for spindle error motion measurement.
Shown is the MCV-500H being used for Laser vector measurement on a JOBS-LINK 5-axis linear motor machine. The laser head is on the bed and the flat-mirror is on the spindle.
The laser system, which registered a frequency stability rating of better than 0.02 ppm and is capable of achieving a measurement accuracy of more than 0.2 ppm, is said to be ideal for high precision machining centers, coordinate measurement machines, and nano metrology.
An improved optical design and measurement range of 100 m makes the system suitable for large, 5-axis gantry type machines or for nano metrology with multiple-pass, according to Optodyne. The system also is said to be ideal for the measurement of robot arm movements, thanks to an optical beam expander that enables a lateral tolerance of +/- 7mm.
Described as compact, easy to setup and operate, the system comes with carrying cases as well as data collection and processing software capable of generating pitch error compensation files for most controllers (Fanuc, Siemens, Forgo, Heidenhain, Mitsubishi).
Related Glossary Terms
- calibration
calibration
Checking measuring instruments and devices against a master set to ensure that, over time, they have remained dimensionally stable and nominally accurate.
- centers
centers
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
- linear motor
linear motor
Functionally the same as a rotary motor in a machine tool, a linear motor can be thought of as a standard permanent-magnet, rotary-style motor slit axially to the center and then peeled back and laid flat. The major advantage of using a linear motor to drive the axis motion is that it eliminates the inefficiency and mechanical variance caused by the ballscrew assembly system used in most CNC machines.
- metrology
metrology
Science of measurement; the principles on which precision machining, quality control and inspection are based. See precision machining, measurement.
- pitch
pitch
1. On a saw blade, the number of teeth per inch. 2. In threading, the number of threads per inch.
- precision machining ( precision measurement)
precision machining ( precision measurement)
Machining and measuring to exacting standards. Four basic considerations are: dimensions, or geometrical characteristics such as lengths, angles and diameters of which the sizes are numerically specified; limits, or the maximum and minimum sizes permissible for a specified dimension; tolerances, or the total permissible variations in size; and allowances, or the prescribed differences in dimensions between mating parts.
- tolerance
tolerance
Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
