Embodiment Construction
[0017] Such as figure 2 As shown, the control device of the groove mill of the present invention mainly includes: a grinding wheel 1, a grinding fluid supply nozzle 2, a workpiece 3, a control part 5, a grinding wheel driving motor 6, an image sensor 8, etc., and the specific structure is as follows:
[0018] A grinding fluid supply nozzle 2 is arranged on the upper part between the grinding wheel 1 and the workpiece 3, and an image sensor 8 is correspondingly arranged on the lower part between the grinding wheel 1 and the workpiece 3 and obliquely in front of the grinding wheel 1. The output end of the image sensor 8 is connected to the control part 5, and the control part 5 is controlled by The motor control part 5b (speed adjustment mechanism), computer image recognition software 5c (judgment mechanism), the image signal generated by the image sensor 8 is input to the computer image recognition software 5c, the computer image recognition software 5c is connected with the mo...

The invention relates to the field of grinding machining, in particular to a grinding method and a control device for a slot grinder. The control device comprises a control part, a grinding wheel driving motor, a proximity sensor and an image sensor. When a grinding wheel is about to make contact with the machining position, the quantity of grinding liquid ejected from the grinding wheel is increased sharply; and the phenomenon that the ejection quantity of the grinding liquid is increased is utilized, the grinding wheel is made to get close to a workpiece at a proximity speed meanwhile the grinding liquid is supplied and grinding wheel rotating is carried out, and when conducting grinding machining in the state where the grinding wheel makes contact with the workpiece, the grinding wheel conducts cut-in feeding relative to the workpiece at a grinding speed lower than the proximity speed. The precision of a traditional sensor utilizing sharp increasing of grinding liquid is not very high, thus, the feedback time is too long, and a grinding wheel is damaged. By adopting the grinding method and the control device for the slot grinder, the grinding control precision is high, and the grinding wheel cannot be damaged due to the fact that the feedback time is short.
Description
technical field [0001] The invention relates to the field of grinding processing, in particular to a grinding method and a control device for groove grinding. Background technique [0002] The original grinding method and the control device of groove grinding: set the judgment mechanism of the contact between the grinding wheel and the workpiece on the grinding machine, and control the cut-in feed speed from the high-speed approaching speed to the low-speed grinding speed with the contact judgment time as the boundary . When performing grinding while the rotating grinding wheel is plunging into the workpiece, it is very important to set the plunging feedrate that matches the target machining accuracy. [0003] However, in these methods, the grinding wheel is brought into contact with the workpiece at the approaching speed by switching the cutting feed rate from the approaching speed to the grinding speed based on the timing when the grinding wheel actually comes into contac...
