||Designation of Code
||Target value of Standard Movement
The value obtained by deducting the nominal movement from standard movement within the effective screw shaft length. As the screw shaft tends to extract due to temperature change and external loading, such value will be determined after correcting the displacement. Such value will depend on experimental or empirical result.
||Typical Movement Deviation
||The value obtained by deducting the standard movement from typical movement.
Corrected axial movement displacement of the nominal movement, which is occurred due to thermal and loading. It leans to physical movement Line.
Physical Movement Line. The straight line calculated by least square method or simple approximation method according to the curve indicated as physical movement.
||The physical movement measured.
|The maximum variations of the physical movement between two straight lines parallel to typical movement will be determined according to the following 3 items.
||Max. variation within effective length of the shaft section.
||Max. variation within 300mm randomly retrieved from effective length of the shaft section.
