Machine Tool Debugging
make the machine tool perform various typical movements for a period of time, and carefully
observe it; when there is no abnormal situation, increase the value gradually; otherwise, decrease
the value and reserve 50% ~ 100% insurance allowance.
14) Turning acceleration: it is used to describe the acceleration/deceleration ability in synchronized
motion of multi-axis, in mm/s

. The value limits the maximum speed of the machine tool in circular
movement. The larger this value is, the higher the maximum allowable speed on circular
movement of the machine tool will be. Generally, for a stepping motor system, the value is
between 400 and 1000; for a servo motor system, the value is between 1000 and 5000; for a
heavy machine tool, the value should be smaller. Set the value smaller at the beginning; make the
machine tool perform various typical movements for a period of time, and carefully observe it;
when there is no abnormal situation, increase the value gradually; otherwise, decrease the value
and reserve 50% ~ 100% insurance allowance.
Usually, given the drive ability of stepping motor, frication of machine assembly, and endurance
capacity of mechanical components, limit the maximum speed of the three axes in actual using by
modifying the max. speed of each axis in manufacturer parameters.
15) Set the parameter of auto lubrication (set a value smaller, such as once every 5 seconds).
Observe if auto lubrication is executed correctly. If so, set it according to the actual need.
If there is any problem in the running of the machine tool, please check every part carefully according
to the steps above of the whole machine debugging.
4.2 Pulse Test
Examine if any pulse is lost. Direct method: mark a little dot on the surface of a workpiece blank with a
dagger; set this point as the workpiece zero; lift up Z-axis; set the coordinate of Z-axis as 0; repeatedly
move the machine tool, for example, run a typical procedure with no tools (including synchronized
movement of the three axes is much better), pause or stop during machining permitted; and then back
to the workpiece zero; descend Z-axis slowly; observe whether the knifepoint matches with the
marked dot. If deviation exists, check the type of pulse signal received by the stepping motor driver
and the connection between the terminal board and the driver. If stagnation or step missing still exists,
please turn to step 13, 14 and 15 to adjust parameters.
