Linear Compensation; Setting The Linear Compensation - Sony LG10 Bedienungsanleitung

6. Linear Compensation

Generally a machine tool has its inherent geometric error.
For example, with a knee type milling machine, the knee is slightly tilted as the table moves and
the horizontal component of this inclination is added to the scale displacement as an error. When
the displayed value is obtained by
corresponding to the actual displacement, the mechanical error is compensated and the more
accurate display is obtained for the actual displacement of the machine table, thus attaining more
accurate machining.
The unit is factory-set so that the linear compensation function does not work.

6-1. Setting the Linear Compensation

The error compensation is made by adding or subtracting a compensation amount to or from the
scale reading for every given table displacement.
Notes on the setting
1) The compensation amounts in Table below apply to a displacement of 1m for the millimeter
2) For a compensation amount not listed in the table, set the closest value.
3) Regarding the polarity, select a positive (+) compensation when the displayed value is

operation and 1" for the inch operation. Be sure to set the compensation amount in the
relevant operation. Precision machining and accurate measurement are not possible if a

smaller than the actual length and a negative (–) compensation when the displayed value is
greater.
