Surface Table Flatness Calibration
Application of our Surface flatness calibration software providing flatness by Union Jack and Grid methods to BS 817, ISO 8512-2 and DIN 876 standards. We provide complete flatness calibration system at an affordable cost to manufacturer.
The Incremental Angular Technique is used as a basis for flatness calibration. Angular data is obtained along prescribed generators using angular instruments such as Electronic Levels, Autocollimators or Laser Interferometers. Various patterns of generators can be selected depending upon requirements. The well known "Union Jack" or Diagonal Configuration in addition to the Linear and Rectangular Grid are available. Angular data input to the program is via the computer keyboard or alternatively if the angular instrument has RS232 or analogue output this may be input on-line.
Flatness Analysis and Specification to any Known Standard.
Flatness data can be analysed with respect to a Gravity, Least Squares or Minimum Zone reference plane. A gravity datum is particularly appropriate for applications relating to the accuracy of Machine Tools and Guideways, whereas the Minimum Zone criterion is required by most of the current test Standards. The results of a flatness calibration can be specified and graded with reference to National or International test standards such as BS 817; DIN 876; ISO 8512-2. Other standards can be set-up by the user as and when required.
