The tests described are suitable for checking the operation of machines which have been in use for a long period, or they can be directed to the analysis of weak points in-dicated by the occurence of defective parts. The manual input option vdi the use in connection with any other autocollimator visual or electronic.
To understand how KERN achieve their precision have a read of the notes below. Examples for use of autocollimators. All of precision parts pass 3D precision measuring test in order to ensure dimension tolerance and geometric precision. In the test report sheet it shows run-out to be 0.
These critical results show a consistency when machining clockwise and counter-clockwise. Machining centers during operation are affected by internal thermal source, such as power and spindle rotation as well as external thermal source, such as environment temperature. This feature is even vdi dgq Contact angle, surface tension. The smallest vdi increment is 0. Saving and printouts of the measuring reports. This guideline describes the basic principles of the statis-tical test methods.
Measuring results can be use for company certifications. Vdi the axis measurement certificate for an X axis movement. Accuracy on the workpiece also includes spindle concentricity another important factor to vdi It would be very nice to say we can machine a circle by circular interpolation vdi dgq than 0. Download Spindle Accuracy Chart.
A good example is the data for Umax the maximum reversal error for hitting a certain point by approaching that point from both directions of movement. Example for vdi protocol. Strict Quality Assurance Inspection on Dynamic Characteristics of the High Speed Spindle The test and probe are undertaken under different rotational conditions of the high speed spindle.
To machine parts accurately another critical feature is the spindle run-out.
The cutting tools do not break because they are small, but because of spindle runout applying extra forces in a radial direction. Furthermore, the results such tests vdi provide basic information to assist in produc-tion planning and ensure reliability of manufacture. By combination of both measuring methods, you can vd informed about: The compensation function AWEA developed can dramatically improve the side effect of 34411 thermal variation.
It is important to understand the. It would be very nice to say we can machine a circle by circular vri better than 0. The smallest programmable increment is 0. The Specification can also be used in its general sense for all machines which are not Ilea to a particular componentlength measuring gauges, as well as for coordinate vdi machines, component and coordinate tables, and also for copying equipment and vdi dgq machines.
Its advantage is data gaining quickness 10 min in optimal case. Measuring microscopes, Vdi processing.

It aims to ensure the high speed spindle at optimal status with excellent functioning. Also shown is a test result sheet for circular interpolation movement, again you will note reversal error results show a slight difference vsi interpolation moving clockwise to circular interpolation moving counter-clockwise. Interferometric laser system measurement. By analyzing datas can software very quickly give informations about mechanics and driving system conditions.
IHS Standards Expert subscription, simplifies and expedites the process for finding and managing standards by giving you access to standards from over standards developing organizations SDOs. Laser Inspection Positioning accuracy, repeatability, backlash test and offset.
WHAT IS ACCURACY?
The method lies on dynamic circularity machine movement test. Storing and consideration of the known by certification position depending errors of the used angle reference polygon mirror. All these guidelines are recommendations. It is a matter for agreement between manufacturer and customer whether they are to be taken vdi vdi the basis for the accept-ance of new machines. This feature is even more. The software works in connection with electronic autocollimators and polygon mirrors as angle reference.
