Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a processing device such as a grinder.

[Summary of the invention]

The present invention visually displays the amount of deflection of the shaft of the grinding wheel of a grinding machine using a display means that graphically displays the amount of deflection, for example, so that the amount of deflection can be easily grasped, thereby making it easier to set and change machining conditions. The aim is to provide an improved processing device.

[Conventional technology]

Conventional processing equipment, such as a grinder, performs rough grinding by repeating trial grinding several times.

The feed rate for each type of grinding head, such as fine grinding and spark out, is as follows:
The feed rate, grinding time, etc. were set, and the machining was controlled by an NC control device or the like based on these set values.

Alternatively, as another method, the fixed dimensions of the workpiece are determined in advance in several stages, and the dimensions of the workpiece being processed are measured using an in-process measurement method, etc., and when the fixed dimensions have been reached, Machining was controlled by inputting signals and converting into various grinding modes, such as from grinding to fine grinding, or from fine grinding to spark out.

[Problem to be solved by the invention]

By the way, it is desirable that the machining state of the grinding machine is such that the deflection of the shaft of the grinding wheel is constant or changes gradually or continuously.

However, in the conventional grinding machine mentioned above, it is not easy to know the amount of deflection of the shaft of the grinding wheel, so it is difficult to appropriately determine each data such as feed amount and feed rate.
There was a problem in that it was difficult to achieve ideal processing conditions.

[Means to solve the problem]

Therefore, in order to solve the above problems, the processing apparatus according to the present invention includes a processing means for processing a workpiece, a control means for controlling the processing means, and a processing state of the processing means or a control amount by the control means in a graphical manner. The present invention is characterized by comprising a display means for displaying the control wave, and an input means capable of inputting or changing the control wave.

[For production]

According to such processing equipment, the operator can visually and easily know the amount of deflection of the tool shaft while looking at a diagram on the display means, so that various data such as the tool feed rate and feed rate can be displayed. It can be determined appropriately and ideal machining conditions can be achieved.

〔Example〕

Embodiments of the present invention will be described below based on the drawings. 1 to 3 are diagrams showing an embodiment of a processing apparatus according to the present invention.

In FIG. 1, 1 is a grinding machine (processing means) that grinds a workpiece, and this grinding machine 1 is equipped with an in-process measuring device 2 that can measure the machined dimensions of the ground workpiece during processing. There is.

In addition, the grinding machine 1 includes a microprocessor 4 (control means).
The microprocessor 4 can control the machining conditions of the workpiece based on the machining dimensions of the workpiece measured by the in-process measuring device 12.

A CRT device 5 (display means) is connected to the microprocessor 4, and the CRT device 5 can graphically display the machining status of the grinding machine 1 or the amount controlled by the microprocessor 4.

Further, a keyboard 7 (input means) is connected to the microprocessor 4, and the keyboard 7 can input or change the amount controlled by the microprocessor 4.

Next, the operation of such a grinding machine 1 will be explained. For the grinding machine 1, the processing conditions such as the processing dimensions of the workpiece at the time of changing the grinding mode (switching point) such as rough grinding, fine grinding, etc., the cutting amount of the grinding wheel, and the cutting speed at that point are roughly determined. , start processing. During this machining, the machining status by the grinder 1 is monitored (projected) on the screen of the CR,T" device 5.

Assume that the screen at that time is displayed as shown in FIG. 2, for example. That is, in the sizing change diagram a, the machining dimensions of the workpiece at the above switching points (sizing switching points 1 to 4)
．． The sizing completion point) is displayed, and in the cut line, the gap feed amount is approximately 120 μm, rough grinding 1 feed amount is 60 μm, ffl grinding 2 feed amount is 20 μm, 11
Sharpening spark out time 2.0 seconds, retraction amount 30
μm.

Seiken 1 feed 4110 μm, Seiken 2 feed amount 5 μm',
'M! The 1 second spark out time etc. will be displayed.

Suppose that under processing conditions with values determined in this way, a swivel diagram C1, that is, a line C that shows the swivel amount (deflection amount) of the grinding wheel shaft over time, is displayed on the screen as shown in the figure. . The cutting line C in the same figure has a shape like a medium-high mountain and is not constant over time, so it can be clearly seen that the cutting amount of the grindstone shaft is also not constant.

By the way, as mentioned above, it is desirable that the cutting amount of the grinding wheel shaft is constant in the machining state of the grinding machine 1, so it is necessary to make corrections in this way. By pressing and operating each key 7, the above values can be changed, for example, as shown in FIG.
■Grinding 2 feed amount
Seiken 2 feed N x eμm, Seiken spark-out time t
By changing the time to 2 seconds, etc., it is possible to correct the cross-section diagram C to a constant value as shown in FIG. The constant value is different before and after retraction, but this is not a problem in the negative direction, but is rather necessary.

After appropriately changing each value to correct the cross-section diagram C in this way, the grinding machine 1 can process the workpiece in an ideal processing condition under the processing conditions based on the values.

In the above embodiment, each value is input as a target value using the keyboard 7, but it is possible to display both the actual value and the target value to check the deviation between them, for example, when the sharpness of the grindstone decreases. It is also possible to detect this and, when the cross-section diagram C is no longer constant, correct it by inputting the target value again so that it becomes constant again.

In addition, in the above embodiment, a case was explained in which measurement was performed using an in-process measurement method that measures during processing.
The measurement may be performed using an aftergauge measurement method that is measured after processing, or both methods may be used in combination.

Furthermore, although the above embodiments have been described with reference to a grinder, there is no need to limit the invention to a grinder, and the present invention may be applied to other processing devices.

〔Effect of the invention〕

As explained above, according to the processing apparatus of the present invention, the operator can visually and easily know the base of deflection of the tool axis while looking at the diagram on the display means, so the feed amount and feed rate of the tool can be easily determined visually. It is possible to appropriately determine each data such as, and to realize an ideal machining state.
