Next, the operation of the present invention constructed as described above will be explained.

First, when cutting the workpiece W with a ramp, the following processing conditions are input to the control device 60 and displayed on the display.

The contents are interactive, and the control device 60 is used for each setting condition.
screen and set conditions in the form of questions.

(a), Weight of weight G (way 1 - cart (kg).

Or convert the load using the distance Mltβ dimension).

Since the weight of the workpiece W and the weight of the weight G are balanced as shown in the schematic diagram of FIG. 20, the weight of the required way) G is set in the pre-game.

As shown in the schematic diagram of FIG. 20, both weights are balanced, and the distance p from the fulcrum shaft 104 to the way I.G is changed using the pulse motor 42 and the pole screw 43. weight), the cutting load is obtained, and the N method of the distance MI[e is set.

Also, from the start of cutting to the end of cutting of workpiece W (load comparison)
Change the load with . For example, 5 to 8 at the beginning of cutting workpiece W.
The dragon is set lightly, the load is increased from the state where the flade 5 cuts into the workpiece W and it sinks, and the charge is further set lightly at 5 to 8 openings at the end of cutting the workpiece W.

(b), Number of work table vibrations per minute.

The number of vibrations seems to change depending on the abrasive quality of the workpiece W, but the cutting speed (per cutting amount) depends on the amount of cutting fluid (semen) inserted between the blade 5 and the workpiece W depending on the number of vibrations. Control 1-roll.

In this case, the surface roughness of the cut surface is also important.

The frequency of vibration changes from the beginning of cutting to the end of cutting. For example, the number of vibrations is set small at the beginning of cutting (cutting width 5 to 8 times), the number of vibrations is increased by 1 from the state where the blade 5 cuts into the workpiece W and sinks, and the number of vibrations is set to be small at 5 to 8 times at the end of cutting.

(C) Stroke amount of the blade (stroke amount during e-stroke (mm)).

The settings are made depending on the size and shape of the workpiece W. Another purpose is to reduce vibrations at both stroke ends due to wear of the blade 5.

This is because the blade 5 also wears out when cutting the workpiece W.
The stroke of the blade 5 is set short to prevent vibration from occurring in the image oscillating width.

(d), Blade speed (number of plate strobes per minute).

If the stroke amount of blade 5 is small, blade 5
Increase the speed of the stroke.

(e) Automatic startup settings.

Execute return to origin and set conditions for each shaft cylinder.

Since the command from the control device 60 is to simultaneously operate one axis, the above-mentioned return to origin and condition setting are performed for each axis.

The above fat ~ (e+ condition settings are such that the machining efficiency is 2 to 3.
Since y=m/time, each cutting amount is set at 1 for 5 of the total machining time.

The above settings can be set to a maximum of 150 hours by the control device 60.
Must be able to program at a certain level.

In addition, if you have experience in machining, please set the settings in ``2'' on the control device 6.
It becomes possible to store 0.

Also, if the initial conditions are unknown, input the data each time.

With the above steps, data processing for each processing condition is completed.

Next, the operating procedure of the U-7pukiri 1+Ji machine will be explained.

First, the work W is mounted on the work table 4. In this case, the same quality as the work W or something similar thereto is pasted on the bottom of the work W and the cent is placed. When attaching the same material as the workpiece W, when the workpiece L7I is cut, the workpiece W and the same abrasive material attached to it are cut halfway with the blade 5, thereby preventing chips or damage at the end of cutting the processed workpiece W. This is to prevent this.

Next, a plurality of blades 5 are placed on the blade support frame 6 of the lap cutting machine main body l. In this case, the processed workpiece W
The thickness of the plate 5 and the thickness of the spacer are set according to the cutting thickness, and the cutting width is also set based on the particle size of the cutting fluid.

The blade 5 is fixed at both ends by blade holders 111 provided on the movable block 107 and the fixed block 108 as described above. At this time, while checking the parallelism and horizontality of the blade 5 with respect to the horizontal movement of the blade support frame 6, the moving block 107 is moved by the bolt 110 via the end plate 109 so that the accuracy is within the specified accuracy.
While applying tension to the blade 5, tighten it to the specified 1-lux using a torque wrench.

The setting of the blade 5 is now completed, and the blade support frame 6
at a predetermined position on the processing table 3, that is, the work table 4
The blade 5 is pressed against the workpiece W attached to the workpiece W, and the blade 5 is picked up in a separated state. Then, on the side of the fixed block 108,
One end of the rod 12 of the variable stroke reach device 10 is fixed via the bracket 11.

The workpiece W is machined by reciprocating the blade 5 while being pressed against the workpiece W by a constant pressure due to the weight of the weight G.

After completing the machining setup as described above, driving of the lamp cutting machine main body 1 is started.

First, cutting fluid (abrasive fluid) is supplied to the cutting part of the workpiece W from the cutting fluid supply device, and the blade 5 is controlled at a constant speed and at a predetermined speed by the variable stroke device IO and the plate speed control device 20. Start cutting with the stroke amount.

Further, the workpiece W is vibrated at a constant frequency by a workpiece full vertical vibration device 30.

Control of the cutting load of the workpiece W is performed by adjusting the position of the weight G by driving the pulse motor 42 in response to a command from the control device 60. That is,
5 to 8 mm at the beginning of cutting the workpiece W is set lightly, and when the plate '5 cuts into the workpiece W and sinks, the load becomes heavier, and furthermore, at 5 to 8mm at the end of cutting the workpiece W, the load f is set.
(i is set lightly.

Further, the blade speed and stroke amount are controlled by a pulse motor @19 and a variable speed drive motor 130 of the speed reducer I1, which are rotated based on commands from the control device 60.

When the cutting of the workpiece W is started in this way, the cutting point is recorded by a detection recording device 50 installed on the shaft 104.
The data is recorded by the potentiometer 51 and the recording device 52, and the recorded data is fed back to the control device 60, into which it has been input in advance, to be corrected and processing is continued.

In this way, the variable speed drive motor 130 cuts the lamp while being controlled based on the recorded data of the detection and recording device 50. Machining is performed automatically.

When the cutting process of the workpiece W is completed due to deep cutting as described above, the detection recording device 50 detects this state and outputs a cutting end signal for the workpiece W, and at the same time, the supply of each axis and the cutting tt is stopped. .

At the same time, the recording device 52 also stops, and the patrol light indicates the completion of processing. Then, each processing operation as described above is performed for each workpiece W, and if the material etc. of the workpiece W is different,
Modify the conditions each time and input them to the control device 60.
do.
