6.1.1. Adjustment of Axial Direction
Firstly confirm the positive direction of each axis according to the coordinate system of right-hand
rule during the process of machine debugging, i.e. the feed motion direction of cutter is relative to the
workpiece which is supposed to be still.
After fixing the positive direction of each axis following the right-hand rules, manually operate the
machine to check if the axis moves correctly. If the direction is opposite, please modify the parameter
“Axis Output Dir”. Take X-axis as an example, manually move X-axis; if you find it moves oppositely,
just change the value of X axis in the parameter “Axis Output Dir” from “Positive (Negative)” to
“Negative (Positive)”.
The method is: press “Menu” key→ select 5. Mfr Param→ select 2. Axis OutpDir, and then press
[OK] key to enter the interface shown in Fig. 6-1.

Adjustment of Pulse Equivalent
Pulse equivalent: the moving distance of workbench or rotation degree of rotary axis
corresponding to one pulse sent by CNC device, the minimum available distance controlled by CNC
system as well. This item can be calculated in terms of information of screw pitch, electronic gear ratio,
mechanical deceleration ratio, etc.
The smaller the pulse equivalent is, the higher the machining precision and surface quality will be.
At the meanwhile, the setting value of pulse equivalent decides the max. feed speed, and the
relationship between pulse equivalent and max. feed speed is shown in the following expression:
Max. feed speed(mm/min) = Pulse equivalent(mm/p)×Hardware frequency(p/s)× 60(s/min)
The hardware frequency of NK105 is 320 KHz; when pulse equivalent is 0.001mm/p, the max.
feed speed of machine tool is 19.2m/min.
