The machining center hand writes a whole circle, who will??

Inner circle or outer circle The center of the circle is in** Do you want to go clockwise or counterclockwise For example, the center of the circle is at the origin Your starting point is x0y-50 You can use g02 j50Actually, here is a circle, and the start and end points coincide and can be omitted.

There will be several rounds of IK commands in the XZ plane, IJ instructions will appear in the XY plane, JK will appear in the YZ plane, and the Mitsubishi system will use the G34 G35 G36 command to locate the hole when drilling. When using G12 and G13 to take the round town key, there will be i, and if it is a Haas system, q and K will appear. I don't know where you said ik.

This is a program of milling circles, add the next knife by yourself, change the radius, you can get the circle you want, arc milling inner circle usually uses g3

First of all, it is necessary to arrange the CNC process flow according to the blank and part graphics, and select the tool. It is then programmed according to the machine system.

First, determine the zero point of the working coordinate system, and the center of the square or circle is x0y0. , the upper surface of the blank z0

The tool is selected as a rod milling cutter with a diameter of 20.

The programming is as follows. Milling program:

Supplement: CNC milling machine is an automatic processing equipment developed on the basis of general milling machine, the processing technology of the two is basically the same, and the structure is somewhat similar. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. Among them, the CNC milling machine with a tool magazine is also called a machining center.

1. Mechanical products plus engineering formula is very simple, most of them are programmed manually, computer programming, it is complicated, generally do not use computer programming mold plus engineering formula, so only computer programming to program.

2. First take the Siemens CNC programming book, and then memorize and understand it, and then try to program it yourself and compare it with the existing product program, so that you can learn faster.

Steps: 1. G90 91 absolute incremental size programming.

1) G90 (modal), G90 is the absolute dimension input, all data correspond to the actual workpiece zero point.

2) G91 (modal), G91 is an incremental dimension input, each dimension corresponds to the previous contour point.

2. G70 G71 Imperial Metric Programming.

G70 inch, G71 meter, according to the needs of the parts drawing, when compiling the parts processing program, you can switch between the imperial system and the metric system.

3. G54 G57 sets the zero offset and establishes the workpiece coordinate system.

G54 G55 G56 G57: Calls 1st to 4th set the zero offset.

4. G17 G18 G19 plane selection command.

1) G17: processing plane x y; (2) G18: processing plane Zx; (3) G19: processing plane Y Z;

Manual programming is from the analysis of the part drawing, the determination of the processing process, numerical calculation, the preparation of the parts processing program sheet, the production of control media to the program verification are all completed manually. It requires programmers not only to be familiar with CNC instructions and programming rules, but also to have CNC machining process knowledge and numerical computing capabilities. For the parts with simple shape, small amount of calculation and few program sections, it is easier to use manual programming, and it is economical and timely.

Hand programming is a type of CNC programming.

Manual programming is from the analysis of the part drawing, the determination of the processing process, numerical calculation, the preparation of the parts processing program sheet, the production of control media to the program verification are all completed manually.

For the parts with simple shape, small amount of calculation and few program sections, it is easier to use manual programming, and it is economical and timely.

Therefore, manual programming is still widely used in point machining or contour machining of straight lines and arcs. For parts with complex shapes, especially parts composed of non-circular curves, list curves and surfaces, it is difficult to program by hand, the probability of error increases, and sometimes even the program cannot be programmed, and the program must be programmed by automatic programming.

The first floor is very right, but it may be a little difficult for beginners to understand, and you have a knife mark when you come out of the circle. To use the arc to enter the knife, and the retract is good, G91

<> this is the program of Siemens, Qitong early quietly bird wheel Zen, fanuc changed to G43

I've been programming by hand before, and I'm pretty self-conscious about it. I program the parts by hand, and use macro programs for surfaces that can be expressed mathematically, and I don't use software as a last resort.
