Parameters Setup Procedure - LIN COMP
Press to select the "LIN COMP" selection menu
LIN COMP menu is designed to allow user to enter the Linear Compensation value of each axis. The entered
value must be in PPM ( Parts Per Million ). If the non-linear error compensation is in active, the Linear
Compensation will not be effective any more.
Linear Compensation value
of each axis is displayed on
the axis display respectively
The linear compensation value is specified in PPM [
P
(arts)
P
(er)
M
(illion) ], an example of calculating
the PPM value are as follows.
1. Measure the error using s step gauge or any other device ( e.g. guage block ) of an accuracy level
higher than the measuring resolution and the machine as a measuring standard. For example,
if you are using an 0.005mm resolution linear scale and the machine is expected to have an accuracy
of 0.02mm, the accuracy level of your measuring standard should be ideally at least one grade
higher, such as 0.001mm resolution and 0.01mm in accuracy.
2. The error must be recoded in metric unit ( um - micron - 0.001mm )
( e.g. we measure the X axis and record an display error of 19um shorter over a length of 500mm )
3. Project the error to over the 1 meter ( 1000mm ) in length
( e.g. in the above example, if measurement is 1000mm, the error will be
19um X (1000/500 ) = 38um )
4. Find the direction of error, if the DRO display longer than the measurement standard, then compensation
value should be NEGATIVE, and vice versa. In this example, we find the DRO display is shorter then the
standard, therefore compensation value should be an positive value, +38.
5. The PPM value is micron error extrapolated over a meter, the M(illion) referred to in calculation is
1 million microns to the meter.
( e.g. in the above example, the entry compensation value should be +38 )
Enter the X compensation value
then press to exist from
"LIN COMP" menu and return to
the top level menu
