Tips: How does the tool setter work?
First of all, we need to understand the hardware part of the tool setter. The principle of the tool setter is equivalent to an inductive switch. It's actually a push-button inductive switch. The difference is that in addition to the sensing signal, it also needs a travel protection signal and a jump setting signal.
The over-travel protection signal means that when the position reaches the travel position, the system will alarm. At this time, the corresponding alarm signal needs to be written in the system program. The jump setting signal will trigger the high-speed jump signal inside the CNC machine system. The normally open and normally closed points of this signal can be set through system parameters.
Work timing of the tool setter:
First, add the tool to the spindle and move to the initial plane position. Then quickly descend to the middle position. It descends from a relatively middle position at a slower speed to a lower position. At this time, the tool head will slowly touch the contact surface of the tool setter. Then return a set height value. The jump setting signal is triggered again, and the tool setting operation is performed by descending. When the second tool setting operation is completed, the spindle will quickly return to the initial plane. At this time, the system will calculate the length difference through two measurements, and compensate the corresponding difference into the tool length compensation.
