4) Fanuc system.

The configured system software has a relatively complete set of basic functions and optional functions. For general machine tools, the basic functions can fully meet the requirements of use. String 9

5) Provide a large number of rich PMC signals and PMC function instructions. These abundant signals and programming instructions make it easy for users to program machine-side PMC control programs and increase programming flexibility. String 5

6) It has a strong DNC function. The system provides a serial RS232C transmission interface, which enables data transmission between the general-purpose computer PC and the machine tool to be carried out easily and reliably, so as to achieve high-speed DNC operation.

7) Provide abundant maintenance alarm and diagnosis functions. The FANUC Repair Manual provides users with a large number of alarm messages, which are categorized into different categories.

is the offset of all coordinate systems. What you set in g54 and g59 only applies to their respective coordinate systems.

Enter a numeric value to offset the workpiece coordinate system.

If it is imported into x, it indicates the right offset of the zero point of the workpiece coordinate system x.

It should be the coordinates of z and y, indicating where it is.

The ext coordinate system is actually just an extension of g53-g59, and in fact it is the same.

ext is the total bias. If you change the ext, the other coordinate systems will also change.

The second floor is correct, if you set the ext coordinate to the deviation value, all the coordinate systems below will add its deviation value.

1. Install the machine bai device edge finder on the spindle.

DU on, in MDI mode.

Rotate down the spindle to run ZHI, M03S500, start the spindle forward rotation DAO500, select the handwheel mode, move the edge finder to the left side of the workpiece, slowly approach the workpiece, the edge deviation of the edge finder gradually decreases, when the deviation is small, select the x1 magnification, as shown in Figure 1, when the deviation is getting smaller and smaller and suddenly becomes larger, close the handwheel as shown in Figure 2.

Fig. 3 Fig. 43 moves the edge finder to the right side of the workpiece, the method is the same as 1, when the edge seeker deviates less and less and suddenly becomes larger, close the handwheel when the edge finder deviates more and more and suddenly becomes larger, as shown in Fig. 5 relative coordinates, as shown in Fig. 6, move the x-axis to the position of the midpoint of the relative coordinates as shown in Fig. 7

Figure 5, Figure 6, Figure 74, set G54 coordinates, press OFS Set key - coordinate system - operation - set ext coordinates xyz to 0 - move the cursor to G54 coordinates X - press X0 - press Measure, the mechanical coordinate value of the current position X vector value is input G54, as shown in Figure 8, Figure 9

1. The No. 1 knife that has been measured BAI length is mounted on the spindle du, and the hand wheel moves the tool to the surface of the workpiece, the tip of the knife is lower than the round rod (the measured diameter is 10mm), and the handwheel magnification is selected x100, a. One hand gently leans the round bar against the cutter, the other hand slowly moves up the Z axis, when the round bar can just pass under the cutter, take out the round bar, the handwheel moves 2 grids in reverse, B selects the handwheel magnification X10, repeat the action of A, when the round bar just passes under the round bar, take out the round bar, close the handwheel as shown in Figure 13 and Figure 14

2. Set the Z-to-value of G54 coordinates, check the length of No. 1 cutter, as shown in Figure 15, press the OFS Set key - coordinate system - operation - move the cursor to the Z-axis of G54 coordinates - press to measure, the mechanical coordinate Z value of the origin of the workpiece coordinates is input into G54, as shown in Figure 16 and Figure 17, because the round bar is 10mm when the tool is set, the coordinates need to be subtracted by 10, press - (10) - press - (+ input) - press to execute as shown in Figure 18 Figure 19To this workpiece coordinate measurement input is completed, as shown in Figure 15

FANUC 0i tool setting method.

1. Open the system and mechanically return the x-z axis to zero and load the tool in turn according to the cutting steps.

2. No. 1 knife (No. 2, No. 3、。。 Similar) knife method.

1) Hit the tool position to the first position (method: press the MDI key, press the PROG (program) key, adjust to MDI mode, type T0100 EOB (insert separator), press the insert (insert) key to run).

2) Movement mode: Cut the blank plane with the turning tool, exit and leave the blank in the positive direction of x, press the ops set (tool repair) button, press the (correction) button, press the (shape) key, type z0, press the (measure) key to generate the tool supplement.

3) Manual method: Cut the outer diameter of the blank with a turning tool, exit and leave the blank in the positive direction of Z (and stop the spindle rotation, measure the outer size) Press the Ops Set (tool repair) button Press the (Correct) button Press the (shape) key Type x** (represents the size measured in the X direction) Press the (measure) key to generate the knife compensation.

Note: When the No. 1 tool is the reference tool, the cutting plane can be cut, and the rest of the tools are touching the flat surface, in order to ensure accuracy, please approach the workpiece by hand. The trial cutting should not be excessive, and it is necessary to ensure that there is enough margin to complete the workpiece.

Experience: Under normal circumstances, most of the alarms on the screen are due to lack of oil and overtravel in the X or Z direction. Solution: Check whether the oil level of the small fuel tank is up to the bottom line, and there is a shortage of oil. Check whether the X or Z position is normal, and manually move it in the opposite direction.

No, I don't feel the need for it. This kind of knife method is not easy to use when it is actually processed. Just for rule artifacts.

I only know that there is a wide number system, and Fanuc does not have this function.

G30 (one-off) format: G28 location coordinates; g30 pn location coordinates; G28 is used to return the reference point of the machine's coordinate system, and G30 is used to return the second to fourth reference points. Above, the coordinate position gives the coordinate value of a point on the way back to the reference point, and the purpose of this is to make it possible for the return reference point operation to avoid certain interference points.

Y 300 230 Starting Point 0 100 400 Figure 7-8: Return to Reference Point Instruction G28 Execution Process x Return of the Second to Fourth Reference Point G30 must be carried out under the premise that the machine coordinate system is established, and the execution method is the same as that of the instruction is usually used to adjust the datum after the tool change. Four.

Return from reference point – g29 (one-time) format: g29 coordinate position; It must be given immediately after the program segment after g28 or g30. The starting point of its work is the reference point, and the position of the 126 mark is the end point coordinates.

G29 starts at a reference point and passes through the middle point of G28 or G30 to the end point.

That's where the first product is.

If the z-axis setting in the two coordinate systems is the same, as long as the tool length compensation is not wrong, the position must be the same.

Please check whether the z-offset of the two coordinate systems is the same, and whether the tool length compensation is the same. Check if there is a local coordinate system defined in the program.

Set up two coordinate systems in the machining center, and it is no problem to adjust the tool compensation correctly.

Did you see with the naked eye that the program went to another coordinate system, and the z-axis was in the opposite direction?
