trends in laser measurement.

by:KJTDQ     2020-05-08
The development trend of laser measurement laser has always been a great gospel of measurement.
Its coherent light allows us to measure a few inches of swing in the sky to be accurate to the speed of a single wavelength away from a long distance and to split hairs in micro molecules. Formetal-
Work, which means a new era of precision equipment that can calibrate tools, digitize prototypes, and measure the size of a few parts per million.
Comments on laser
Based on measuring instruments and systems will help to reveal the effect of laser measurement on metalsworking.
A new type of laser digitizer for vertical milling machines and machining centers is replacing the traditional stylus.
The results demonstrate the accuracy and speed of the set size measurement (gridof points)
Surface information for tool manufacturing.
It is combined with the machine controller, enabling the user to select a variety of cutting tools for the task at hand, in addition to the flexibility to modify or operate surface information, to improve the profile or shape details of the mold, pattern, mold, model or prototype.
The laser probe transmits the measured data 30 times faster than the mechanical digitization.
This information is stored on the hard drive and is used by the controller to guide the cutting operation.
The laser probe provides optional machine accessories and has the following advantages: 1.
The precision of the mold is improved. 2.
Increase tool productivity (
In the ratio of 8:1)
Faster digitization. 3.
A scan problem, create a toolpath for any type of tool and left-or right-
Manual parts that allow to shrink and stretch the mold size. 4.
For further analysis or shape modification, it is easy to download surface data to a cad/CAM workstation.
Previously, contact probes measured these dimensions and part shapes, moving along the part in constant physical contact.
Because the probe can\'t be hard-to-
Data is usually incomplete.
In addition, the cutting capacity of the mechanical probe is very limited.
In contrast, the laser probe eliminates many of these defects.
It is mounted on the main shaft of the mill or machining center
Semi-State equipment
Continuous scanning produces high density measurement points.
It emits a laser beam at a fixed distance (focalpoint)from the part.
This distance is the basis for the dimensional measurement of interpolation to define the shape and form of the part.
When the machine moves the probe on a scan track, the data is stored in the hard disk of the host.
Then process this data and create tool paths for rough machining and finishing operations using various tools (
Including ball nose, cow nose, flat nose, cone nose).
After the scan is completed, remove the probe from the spindle and use the tool instead to start milling.
The machine operator enters the required cutting parameters and begins the machining cycle. An AT-
The compatible PC stores the size data and numeric code on the hard drive and offloads it to the machine controller viaa high-as needed-speed RS-232 link. The laser-
Digital probes can be transformed into existing vertical milling machines and centers.
