5-5. 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
measuring unit displacement as an error. When the displayed value is obtained by adding an error compensation
corresponding to the actual displacement, the mechanical error is compensated for and a more accurate
display value is obtained for the actual displacement of the machine table, thus yielding more accurate
machining.
The unit is factory-set so that the compensation function is not activated.

Linear compensation

If the compensation value is not known, set the compensation value to OFF in the "detailed settings", and
redo the settings after measuring the compensation value.
5-5-1. Linear Compensation
The linear compensation is set using the following process.
Measure the compensation (error) value t Set the linear compensation value ("Detailed Settings")
Compensation amount : up to ±600 um/m (can be entered in measuring unit input resolution units)
The compensation amount is a displacement of 1 m for the millimeter operation. Input the value as millimeter
unit.
Error (compensation) measurement (Linear compensation)
Following is an example of machine error measuring procedures for determining the amount of compensation.
1
Place a block gauge A on the machine table until the block gauge A assumes the same temperature as
the machine table.
Then touch the surface B of the block gauge A with a block gauge B.
Example: L = 250 mm (L = 9.84250 in)
