The invention relates to the field of machine tools, in particular to an intelligent numerical control machine tool.
[ background of the invention ]
A typical machine tool has a high-speed spindle and a frequency converter for driving the high-speed spindle. During operation, an operator firstly combines the cutter on the high-speed main shaft, and then starts the frequency converter to enable the high-speed main shaft to drive the cutter to rotate, so that a workpiece is machined.
However, since a general machine tool can be operated only at a fixed setting, for example, only with a fixed-size tool and at a fixed rated operating current, the general machine tool cannot efficiently machine a workpiece when a work load becomes large or small. In addition, a typical machine tool, when activated, causes the tool to continue to rotate, regardless of whether the machine tool is working on a workpiece, thereby wasting a lot of unnecessary electrical energy.
To solve the above problems, a novel machine tool control mechanism is needed in the art.

the microcontroller is used for enabling or disabling the frequency converter, determining the rated working current according to the size specification of the cutter and transmitting the information of the rated working current to the frequency converter; and
a working area for carrying the workpiece and having a proximity detector;
when the proximity detector detects that the distance between the workpiece and the cutter is smaller than a default value, an enabling signal is sent to the microcontroller to enable the frequency converter, and when the proximity detector detects that the distance between the workpiece and the cutter is not smaller than the default value, an disabling signal is sent to the microcontroller to disable the frequency converter.
