<p>This standard is intended for use when the run-out accuracy of the moving parts of electron beam welding machines</p>
<p>complying with EN ISO 14744-1 is to be measured in connection with an acceptance inspection. It provides</p>
<p>information on the procedure and apparatus to be used for making the measurements. Given the great variety of</p>
<p>electron beam welding machines, the scope of measurements required for acceptance inspection purposes should be</p>
<p>specified separately for the machine concerned.</p>
<p>Run-out accuracy as defined here is a systematic error and thus counts as one of the parameters by which the</p>
<p>performance of a machine tool can be characterized. Other factors influencing performance (e.g. dynamic forces,</p>
<p>vacuum level, positioning accuracy of CNC machines) and methods of statistical evaluation are not covered in this</p>
<p>standard.</p>
<p>Electron beam welding involves movement of the workpiece and/or of the electron gun. Successful welding</p>
<p>presupposes that this movement is effected by the devices concerned (e.g. work table and rotating fixture) with a</p>
<p>given degree of accuracy. The purpose of the measurement is thus to check whether and to what extent the required</p>
<p>run-out accuracy is maintained.</p>
