FANUC NC system function introduction
1, control the number of tracks (FANUC Controlled Path)
CNC control of the feed servo axis (feed) the number of groups. Processing each group to form a tool trajectory, each group can be a separate movement, but also coordinated movement.
2, control the number of axes (FANUC Controlled Axes)
CNC control of the total number of feed servo axes / each track.
3, the number of linkage control (FANUC Simultaneously Controlled Axes)
The number of feed servo axes that are interpolated at the same time for each track.
4, PMC control axis (Axis control by FANUC PMC)
The feed servo axis controlled by the PMC (Programmable Machine Controller). The control instructions are programmed in the PMC program (ladder diagram), so the modification is inconvenient, so this method is usually used only for the movement of the fixed axis control.
5, Cf axis control (Cf Axis Control) (FANUC T series)
In the lathe system, the rotary position (corner) of the spindle is controlled by the feed servo motor as well as other feed axes. The axis is interpolated with other feed axes to process any curve.
6, Cs contouring control (Cs contouring control) (FANUC T series)
In the lathe system, the rotary position (corner) control of the spindle is not implemented by the FANUC spindle motor with the feed servo motor. The position (angle) of the spindle is detected by a high-resolution encoder mounted on the spindle (not the spindle motor). The spindle is operated as a feed servo axis at a speed of: degrees / min and with other feed axes Together with the interpolation, processing out the contour curve.

7, rotary axis control (Rotary axis control)
Set the axis to the rotary axis for angular position control. Rotate the angle of the week, the available parameter is set to any value. FANUC system is usually only the basic axis outside the feed axis can be set to rotary axis.
8, Controlled Axis Detach
Specifies that a feed servo axis is out of control of the CNC without system alarms. Usually used for turntable control, the machine does not use the turntable when the implementation of the function of the turntable motor plug unplugged, remove the turntable.
9, servo off (Servo Off)
The power supply to the servo axis is turned off with the PMC signal, which is free to move away from the CNC's control, but the CNC still monitors the actual position of the axis in real time. This function can be used to control the movement of the workbench on a FANUC CNC machine with a mechanical handwheel or a table when the turntable is mechanically clamped to avoid overcurrent in the feed motor.
10, position tracking (Follow-up)
If there is a mechanical position in the table when the servo is off, the emergency stop or the servo alarm, there will be a position error in the CNC position error register. The position tracking function is to modify the machine position monitored by the CNC controller so that the error in the position error register becomes zero. Of course, the implementation of location tracking should be based on the actual control needs.
11, incremental encoder (Increment pulse coder)
Rotary (angle) position measurement element, mounted on the motor shaft or ball screw, the rotation is issued when the interval pulse that displacement. Since there is no zero on the code wheel, it can not indicate the position of the machine. Only in the machine back to zero, the establishment of the machine coordinate system after the zero, to show the location of the table or tool. It should be noted that the incremental encoder signal output in two ways: serial and parallel. The CNC unit corresponds to a serial interface and a parallel interface.
12, absolute encoder (Absolutepulse coder)
Rotary (angle) position measuring element, the same use and incremental encoder, the difference is that this encoder code has an absolute zero point, the point as the pulse count reference. So the count value can either reflect the amount of displacement, but also can reflect the actual location of the machine in real time. In addition, the location of the machine after the shutdown will not be lost, do not have to return to zero after starting, you can immediately put into the processing run. As with the incremental encoder, use the serial output of the pulse signal and the parallel output to match the interface of the CNC unit. (The early CNC system has no serial port.)
13, FSSB (FANUC serial servo bus)
FANUC Serial Servo Bus (FANUC Serial Servo
Bus is a signal high-speed transmission bus between the CNC unit and the servo amplifier. A cable can be used to transmit control signals of 4-8 axes. Therefore, in order to distinguish the axes, the parameters must be set.
14, simple synchronous control (FANUC Simple synchronous control)
One of the two axes is the master axis, the other is the slave axis, the drive axis receives the CNC's motion command, and the slave axis follows the active axis movement to achieve simultaneous movement of the two axes. The CNC monitors the movement of the two axes at any time, but does not compensate for the error. If the movement of the two axes exceeds the set value of the parameter, the CNC will send an alarm and stop the movement of each axis. This function is used for biaxial drive of large workbench.
15, dual drive control (FANUC Tandem control)
For a large table, a motor torque is not enough to drive, you can use two motors, which is the meaning of this function. One of the two axes is the master axis and the other is the slave axis. The master axis receives the CNC control command and the slave axis increases the drive torque.
16, Synchrohouus control (FANUC T series of dual-track system)
The dual-track lathe system enables the synchronization of two axes of a track, as well as the synchronization of the two axes of the two tracks. The synchronization control method is the same as the above "simple synchronization control".
17, composite control (Composite control) (FANUC T series of dual-track system)
The double track of the lathe system allows for the realization of the trajectory of the two trajectories, i.e. the first trajectory of the program can control the movement of the second trajectory; the second trajectory of the program can control the first trajectory of the axis movement.
18, super-lighting control (T series of dual-track system)
Double track lathe system, can achieve two tracks of the axis movement instructions simultaneously. The difference from the synchronous control is that the synchronous control can only send the motion command to the master axis, and the overlap control can either send the command to the master axis and send the command to the slave axis. The amount of movement of the slave shaft is the sum of the amount of movement of the slave axis and the movement amount of the master axis.
19, B-Axis control (T-series FANUC)
The B-axis is an independent axis added to the basic axis (X, Z) of the lathe system for the turning center. Which is equipped with a power spindle, so you can achieve drilling, boring or working with the basic axis at the same time to achieve complex parts processing.
20, Chuck / Tailstock Barrier (T Series)
This function has a setting screen on the CNC's display. The operator sets a tool entry area according to the shape of the chuck and tailstock to prevent the tool nose from colliding with the chuck and tailstock.
21, Tool post blow check (T series)
In a double track lathe system, this function can be used to avoid collision between two tool holders when machining a workpiece with two tool holders. The principle is to use the parameters set the minimum distance between the two tool holders, processing from time to time to check. Stop the feed of the tool holder before a collision occurs.
22, abnormal load detection (Abnormal load detection)
Mechanical crashes, tool wear or breakage can cause large load moments to the servomotor and spindle motors, which may damage the motor and the drive. This function is to monitor the motor load torque, when the parameter exceeds the set value in advance to stop the motor and reverse the return.
23, hand handle interruption (Manual handle interruption)
Shaking the handwheel during automatic operation increases the movement distance of the movement axis. For correction of stroke or size.
24, manual intervention and return (Manual intervention and return)
During automatic operation, stop the feed axis with feed pause, and then manually move the axis to a position to do some necessary operation (eg tool change). Press the auto start button after the operation to return to the original The coordinate position.
25, manual absolute ON / OFF (Manual absolute ON / OFF)
This function is used to determine whether or not the coordinate value manually moved after the pause is added to the current position value of the automatic operation during automatic operation.
26, hand wheel synchronous feed (Handle synchronous feed)
In automatic operation, the feedrate of the tool is not the speed specified by the machining program, but is synchronized with the rotational speed of the hand pulse generator.
27, manual digital command (Manual numeric command)
The CNC system is designed with a dedicated MDI screen through which the motion instructions (G00, G01, etc.) and the amount of movement of the axes are entered using the MDI keyboard, and these instructions are executed by the JOG (manual continuous) feed mode.
28, spindle serial output / spindle analog output (Spindle serial output / Spindle analog output)
Spindle control has two kinds of interfaces: one is the serial transmission of data (CNC to the spindle motor instructions) interface called serial output; the other is the output analog voltage as the spindle motor command interface. The former must use the FANUC spindle drive unit and the motor, the latter with an analog control of the spindle drive unit (such as the frequency converter) and the motor.
29, spindle positioning (Spindle positioning) (T system)
This is a way of working for the lathe spindle (position control mode), with FANUC spindle motors and position encoders mounted on the spindle to achieve fixed angular intervals on the circumference of the positioning or positioning of the spindle at any angle.
30, the spindle orientation (Orientation)
In order to perform spindle positioning or tool change, the machine tool spindle must be positioned in the circumferential direction of rotation and on a certain angle as the reference point of the action. This function of the CNC is called spindle orientation. The FANUC system provides the following three methods: orientation with a position encoder, orientation with a magnetic sensor, orientation with an external turn signal (eg proximity switch).
31, Cs Contour control (FANUC Cs Contour control)
Cs contour control is to change the spindle control of the lathe to the position control to realize the positioning of the spindle according to the rotation angle, and can be interpolated with other feed axes to produce the workpiece with complex shape. Cs axis control must use FANUC serial spindle motor, in the spindle to install high-resolution pulse encoder, therefore, with the Cs axis spindle positioning accuracy than the above-mentioned spindle positioning accuracy.
32, multi-spindle control (Multi-spindle control)
The CNC can control the other spindles in addition to the first spindle, up to four controls (depending on the system), usually two serial spindles and one analog spindle. The control command S of the spindle is determined by the PMC (ladder).
33, Rigid tapping (FANUC Rigid tapping)
The tapping operation does not use the floating chuck but is achieved by the synchronous operation of the spindle rotation and the tapping feed axis. The spindle rotates one turn and the tapping shaft feeds equal to the pitch of the tap, which improves accuracy and efficiency. To achieve rigid tapping, the position encoder (usually 1024 pulses per revolution) must be installed on the spindle and a corresponding ladder diagram is required to set the relevant system parameters. Milling machine, lathe (turning center) can achieve rigid tapping. But the lathe can not be the same as the milling machine to achieve anti-tapping.
34, spindle synchronization control ( FANUC Spindle synchronous control)
This function can realize the synchronous operation of two spindles (serial), in addition to speed synchronous rotation, but also to achieve the rotation phase synchronization. With phase synchronization, two irregularly shaped workpieces can be clamped on the lathe with two spindles. According to the different CNC system, can achieve a track within the two spindle synchronization, but also to achieve two tracks in the two spindle synchronization. The spindle that accepts the CNC command is called the master spindle, and the main spindle is rotated back to the spindle.
35, spindle simple synchronous control (FANUC Simple spindle synchronous control)
Two serial spindles run synchronously, accepting the spindle of the CNC command as the main spindle, and following the main spindle to operate from the spindle. The two spindles can be rotated at the same speed at the same time, and can be operated at the same time for rigid tapping, positioning or Cs axis contour interpolation. Unlike the spindle synchronization described above, simple spindle synchronization does not guarantee synchronization of the two spindles. The simple synchronization state is controlled by the PMC signal, so the corresponding control statement must be programmed in the PMC program.
36, the spindle output switch (FANUC Spindle output switch) (T)
This is the spindle drive control function, the use of special spindle motor, the motor stator has two windings: high-speed winding and low-speed winding, with the function to switch the two windings to achieve a wide constant power speed range. Winding for relays. The switching control is implemented by the ladder diagram.
37, tool compensation memory A, B, C (Tool compensation memory A, B, C)
The tool offset memory can be set to any of the A, B, or C types. Type A does not distinguish between geometric shape compensation and wear compensation for the tool. Type B is to separate the geometric shape compensation from the wear compensation. In general, the geometric compensation is the difference between the measured tool dimensions; the wear compensation is the difference between the dimensions of the workpiece. Type C not only separates geometric compensation from wear compensation, but also separates the tool length compensation code from the radius compensation code. The length compensation code is H and the radius compensation code is D.
38, tool nose radius compensation (T)
The tool nose has a circular arc, in order to precise turning, according to the direction of the direction of the tool and the relative position between the tool and the workpiece to compensate for the radius of the nose.
39, three-dimensional tool compensation (Three-dimension tool compensation) (M)
In multi-coordinate linkage machining, the tool can be offset in three coordinate directions during tool movement. Can be achieved with the tool side of the compensation, but also to achieve the tool with the end of the compensation.
40, tool life management (FANUC Tool life management)
When using more tools, the tool is grouped by its life and the order of use of the tool is pre-set on the tool management table of the CNC. The tool used in machining can automatically or manually replace the same group when it reaches the life value
