FANUC machining center is solved in one section

Brother just learn manual programming, hehe g76 is boring Q1It should be written as good, for the hole boring, the xy axis is good, and then the knife is lifted up, just to avoid the knife particles rubbing on the workpiece when the knife is raised, remember that z-100 should be added, I wish you success in learning.

The G76 of the FANUC system is a thread cutting cycle;

The q of the first segment of the program represents the minimum depth of cut in the radius direction;

The q of the second part of the program represents the first depth of cut radius designation;

There is also a problem with the format of your program.

G76 is in the following format

g76 p q r;

g76 x z p q f;

This is one of the more commonly used boring programs.

q1.In G76 or G86, it is expressed as the spindle positioning tool is set back 1mm after the boring knife reaches the bottom of the hole. In this way, there will be no knife marks on the wall of the hole.

FANUC system.

G76 fine boring.

You read this program in a book, Q1 is a retract value of 1 mm (in the positive direction of X) to avoid scratches. And the best. It mainly depends on how big the hole you bored.

If you use g99, you will retreat to point r, for example at r5（z5.Location.

G76 is the boring cycle:

x50 y50 z-100: coordinate location.

R5: The safety distance is 5mm

Q1: In order to give way, in order to avoid the tip of the knife from scratching the surface of the workpiece, or it is appropriate.

F500: The feed rate is 500 per minute (but in the G94 state, G94 is fed per minute).

Note: Does this app work??? Can it be processed???

The colleague on the first floor said it very well, but it was not detailed.

It's very possible that the system of the machining center is different, and I've done machines without adding points.

If you want to add some points, the z-100 is fine, but the knife can't go down The important thing is that Q1 you must change it to Q1, which is dangerous, and I guess this program is so fast to process aluminum.

The vertical x-axis of the rotation direction is called: a axis, and the command is a (the degree of rotation behind it, that is, the coordinate value) to make it rotate.

The vertical y-axis is called: the b axis, and the command is b, so that it rotates.

The vertical z-axis is called: the c-axis, and the command is c, so that it rotates.

Take a z0 point, which is commonly known as the origin of machining, as a reference value, and the tool behind this point to the tool, how much difference in length compensation is made.

In fact, each machine tool tool has a little difference, and the tool is a highly experienced machine tool operation. Here we can only talk about the principle of knife alignment theoretically. Let's take the Fanuc OI sequence, for example.

If the knives are already loaded on the magazine, there are three knives, T1, T2, and T3. First, run Ti M6 in MDI mode. Change the No. 1 tool Switch the handwheel mode Move the tip of the tool down to a certain place (on the backing plate, on the surface of the workpiece, etc.), so that the round bar of a certain diameter (with a 10 mm milling shank can also be used) can just slide between the tip of the tool and the plane (it is necessary to have a certain amount of experience to control it). Then press the POS button on the machine panel, then press the software until the relative coordinate screen is displayed, then press the Z key on the panel, and then press the Origin button on the soft key.

You can see that the coordinate value in the z direction is 0. Press the offset setting on the panel and press the software to change until the tool length screen is displayed. Set the length of the first knife to 0.

Then change the MDI mode to run T2 M6; Then use the handwheel to move the tip of the second knife to the same plane as the first knife and let the round bar just slide through (it must be in the same plane as the ti, this is very important), press the offset setting on the panel and press the software to change until the tool length screen is displayed. Enter the value of the relative coordinates on the length of the No. 2 knife (you can also press the C input key of the soft key) so that the No. 2 knife is right. Then change the MDI mode to run T3 M6; Then use the handwheel to move the tip of the second knife to the same plane of the first knife, let the round bar just slide through, press the offset setting on the panel, and press the software to change until the tool length screen is displayed.

Enter the value of the relative coordinates on the length of the No. 3 knife (you can also press the C input key of the soft key) so that the No. 3 knife is right. If there are more knives, the method is the same. The above is the method of using the relative knife length.

In a word. It means that if the tool length of Ti is 0, then what is the tool length of T2 (that is, the value measured by the machine), and what is the tool length of T3.

The vertical x-axis of the rotation direction is called: a axis, and the command is a (the degree of rotation behind it, that is, the coordinate value) to make it rotate.

The vertical y-axis is called: the b axis, and the command is b, so that it rotates.

The vertical z-axis is called: the c-axis, and the command is c, so that it rotates.

The fourth axis depends on how you place it (it doesn't matter which system you have, the system supports the fourth axis and you can configure it.) Standard: The direction of rotation is vertical x-axis called:

A axis **a (the number of degrees of rotation at the back, that is, the coordinate value) The vertical y-axis is called: B-axis **B The vertical z-axis is called: C-axis **c

The optional three-axis can be matched. Yes a
