The machining center goes to the outer circle, and the wire cutting processing is in the outer circl

If you just do it, you don't need to use a knife to make up, if your coordinates are in the center of the circle, then the program is wrong, Also, this is not called macro, generally speaking, the macro program is the kind that you can calculate, g1 g91 f20 in your program is useless, if the radius of the outer circle you do is 10, you should program it should be g2 i (10 + tool radius), and the radius behind i is exactly negative depends on the center in front of you to that side, you can first improve the z direction to try the program, You can see how the knife goes, see if the absolute value coordinates are correct, and you can also look at the graph, or lock the machine tool to follow the program.

(X negative goes to the inner circle, positive one goes to the outer circle).

Simulate the tool pass on the machine or use the software on the computer to process it first.

As the saying goes, the master leads the door to cultivate in the individual, if you don't even know the door, no matter how much you teach, it's useless ......

The question you're asking isn't a question at all......I didn't do 1,000 of this kind of homework when I studied at night, and I did it 800 times in the internship workshop

Haha··· Also programmed by hand...

But a round handiwork is also quite fast.

Three points can be used as a garden, the automatic touch of the machine tool, write down more than three coordinates, and then use the three-point circle command on the CAD to find the center of the circle, and then use the excess coordinate value to check whether the position of the center of the circle is accurate.

If the machine doesn't touch the edge automatically, touch it manually.

For example: the first point touches the spark and then sets the number (

The second point, change the position to touch the spark, do not set the number, only remember the coordinates (the third point, continue to change the position to touch the spark, do not set the number, remember the coordinates (the fourth point, continue to change the position to touch the spark, do not set the number, remember the coordinates (now get four sets of values, to the computer with the command of the three-point circle to make a circle, enter the first three coordinate values, the circle has been drawn, now in the fourth coordinate value to test the error of the edge, with the line command input (get a y direction extension line, the line on the circle of the intersection coordinates captured and recorded, You can get the edge collision error. The value I got was (this error is there, but I drew it on CAD, there will be no error, and the actual edge value cannot reach this accuracy. Now that the circle has been drawn, its center coordinates and radius values can be obtained by means of primitive identification or snapping.

In order to get the value accurately, try to ensure that the size of the spark is consistent each time, and you can touch more points to check the coordinates of the position of the center of the circle, and you can also take the average value.

Touch the two sides of the x-axis of this outer circle with a spark divided by 2, and the two sides of the y-axis divided by 2,

I don't understand what you mean, your question is vague.

Finishing is an ultra-precision machining method that is performed after finishing. It is suitable for some parts with high precision and surface quality requirements. As a reversible surface, a variety of different forming methods can be used, so there are many processing solutions available.

However, the machining accuracy, surface roughness, productivity and processing cost that can be achieved by each machining scheme are different, so the most appropriate machining scheme must be selected according to the specific situation to process the parts that meet the requirements of the drawing.

Shafts, sleeves, and disc parts are typical parts with an outer surface. Commonly used machining methods for external surfaces include turning, grinding, and various finishing methods. Turning is the most economical and effective processing method for the outer surface, but in terms of its economic accuracy, it is generally suitable as a rough and semi-finishing method for the outer surface; Grinding is the main finishing method of the outer surface, especially suitable for the finishing of various high hardness and quenched parts; Finishing is an ultra-precision machining method (such as rolling, polishing, grinding, etc.) after finishing, which is suitable for some parts that require high precision and surface quality.

Due to the different economic processing accuracy, surface roughness, productivity and production cost that can be achieved by various processing methods, it is necessary to select reasonable processing methods according to the specific situation, so as to process qualified parts that meet the requirements on the parts drawing.

Turning, grinding, surface roughness, superfinishing, rolling. Turning is the most economical and effective processing method for the outer surface, but in terms of its economic accuracy, it is generally suitable as a rough and semi-finishing method for the outer surface;

The outer surface is the main surface of the rotary body parts (shafts, sleeves, discs). Commonly used machining methods for external surfaces include turning, grinding, and various finishing methods. Turning is the most economical and effective machining method for cylindrical surfaces due to the large thickness of the cutting layer and the large feed.

Although high machining accuracy and machining quality can also be obtained by turning, it is generally suitable for roughing and semi-finishing of external surfaces in terms of economic accuracy. Grinding is the main finishing method for the outer surface with high cutting speed and small amount of cut, and is suitable for various high hardness.

Make a wire hole three on the outside, first cut the inside and then jump out to cut the shape, draw two concentric circles, that is, one large and one small, and finally cut out the finished product is like a washer.

Wire electrical discharge machining (WEDM), which belongs to the category of electrical processing, was developed by the former Soviet Union Lazarenko and his wife when they studied the phenomenon and causes of the damage caused by spark discharge corrosion of switch contacts, and found that the instantaneous high temperature of the electric spark can melt and oxidize the local metal and be corroded, thus creating and inventing the EDM method. The wire cutting machine was also invented in the former Soviet Union in 1960, and China was the first country to use it for industrial production.

Principles of Physics. Free positive ions and electrons accumulate in the field, quickly forming a conductive channel that is ionized. At this stage, an electric current is formed between the two plates. As a result, numerous collisions between the particles form a plasma region, which soon rises to a high temperature of 8,000 to 12,000 degrees, instantly melting some material on the surface of the two conductors, and at the same time, due to the vaporization of the electrode and the dielectric liquid, a bubble is formed, and its pressure rises regularly until it is very high.

Then the current is interrupted and the temperature drops suddenly, causing the bubbles to turn inward**, and the resulting power throws the melted material out of the crater, and then the corroded material re-condenses into small spheres in the dielectric solution and is discharged by the dielectric solution. Then through the monitoring and control of NC control, the servo mechanism is executed to make this discharge phenomenon uniform and consistent.

Punch a wire hole three outside! Cut the inside first, then jump out and cut the shape! You want the same program! Draw two concentric circles, that is, one large and one small, and the final cut out is like a washer! The problem is that it's a bit cold! Hope it helps!
