An analog I/0 module using analog values and a positioning module for control of turrets, ATCs, APCs and other peripherals are also provided.
The required module can be incorporated according to specific needs. Because use of an I/0 unit eliminates the need for relays and a connector panel, a simple magnetics cabinet can be created.

Ladder Diagram Display
When using ladder diagram type programs, it is possible to display the ladder on the CRT screen. Display can also be prevented by a special lock feature. So-called dynamic display is performed and it enables us to monitor switching status of contacts.

Interface With Host Computer,
The following types of communication can be conducted with the host computer, thus permitting easy conversion to a FA system.
Upload and download of NC part programs Message exchange Exchange of PMC control relay, keep memory status

Custom Macro: Software Enabling Incorporation of Specific Machine Knowhow
With custom macro(body) the user can program, store, recall and execute his own automatic cycles, etc. In other words, the user or machine tool builder creates his own software, thereby permitting unique software designed to match the needs of the given NC machinetool, for enhanced functional expandability and individually tailored work capability.
Custom macro features the following capabilities.
Use of variables
Inter-variable calculations: arithmetic, trigonometry, square roots, absolutes, decimal/ binary conversions, etc.
Conditional/unconditional jumps Exchange of I/O signals with the PMC Reading/writing of tool offset and workpiece zero offset values Reading of current positions, skip positions. Naming of variables and display on the CRT External output of variable values and character ters via reader/puncher interface
The registered custom Macro can be locked to prevent unauthorized access
Pocket machining can be simply performed by using custom macro. Once the custom macro is stored, only parameter input is required to perform pocket machining.
Custom Macro Interrupt During execution of program commands, custom macro body can be called using input signals from the machine side. This enables features such as automatic resumption of machining after automatic tool changing has been performed in response to detection of tool breakage.

Digital Servo Drive Enabling
Thanks to the adoption of full digital control in the Fanuc AC servo motors control circuitry and the incorporation of GE Fanuc's independently developed high-precision pulse coder featuring a fast operating speed of 100.000 pulse/rev. GE-Fanuc Series 10/11/12 offer a high cutting speed of 24m/min with outstanding 0.1 resolution.

AC Spindle Motors Ideally Adapted to Fast Spindle Speeds
Full digital control has been adopted in the control circuitry of AC Spindle Motors. Besides making it possible to change the maximum Spindle speed and output values using parameters, digital control also results in improved transient responses and greater rigidity during orientation.

Rigid Tapping
Unlike conventional tapping, which simply performs speed control in order to rotate spindle, rigid tapping also controls position. In this respect, it controls the spindle motor just like a feed motor, causing the spindle to move perfectly synchronous with the movement of the Z-axis. Rigid tapping also enables outstand ing speed and precision without the use of a special tool (floating tapper) as previously. The adoption of a new operating method (patent pending), in which the acceleration/deceleration time constant is changed according to spindle rotation speed, permits tapping over a wide range of speeds, with optimum machining time.

Spindle Positioning
With this feature, the spindle can be positioned to any angle using the spindle motor. No servo motor is necessary.

Accelerating/Deceleration Control Enabling Smooth Machine Operation for Outstanding Cutting Precision
When a machine is operated at high speed, it is inevitably subject to shock during start-ups and stops. To alleviate this problem, GE Fanuc Series 10/11/12 have been specially engineered with advanced acceleration/deceleration control enabling smooth machine operation for outstanding machining precision. During arc cutting, acceleration/deceleration results in error in the radial direction as shown in the illustration at the below. Linear acceleration/ deceleration after interpolation can reduce error to only 1/12 as compared with exponential acceleration/deceleration after interpolation. Linear acceleration/deceleration before interpolation is possible to completely eliminate error caused by acceleration/deceleration. But in contrast with acceleration/deceleration after interpolation which demands no special considerations in the program in terms of acceleration/deceleration, acceleration/deceleration before interpolation is necessary to provide the program with a deceleration start command.

Abundant Functions to Compensate Machine Induced Errors in Precision
Stored pitch error compensation With this feature, compensation is carried out for errors relating to mechanical po sitioning, such as Leadscrew pitch error.
Compensation data is stored in the NC memory in the form of parameters, thereby eliminating the need for a dog or other compensation mechanism.
Inclination compensation Leadscrew pitch error can be compensated using a method involving tri-linear approximation. This features greatly simplifies operations by reducing the number of setting points required as compensation data. In cases where pitch compensation by itself is insufficient, it is also possible to set data for additional compensation using above "stored pitch error compensation".

Backlash compensation
This feature compensates "lost motion" in mechanical operations.
Straightness compensation Machining precision deteriorates if two axes are not maintained at an exact 90° angle. To prevent such misalignment, it is possible to perform compensation on one axis in accordance with the movement of the other axis.

High Efficiency Machining
Overide Playback
During automatic memory operation, the feedrate override and spindle speed override values can be stored (taught) in the command program to permit override operation (play- back) according to the instructed data during the subsequent machining process.

Load Meter Display
Bar graphs showing the load (torque) values of the spindle and servo motors are displayed on the CRT. With the 14" CRT, fluctuations are graphically displayed for the past 1 minute.

Tool Retraction and Recovery
This function is provided to enable the retraction of a tool which breaks during machining in order to permit the operator to change the tool and check machining status. Recovery enables efficient return to the original position for resumption of machining. (1) Activate the "TOOL RETRACT" switch on the machine operator's panel. The tool will retract by the amount commanded in the program and operation will be automatically suspended. (2) Move the tool manually. The path of movement is automatically memorized by the controller. (3) Turn on the switch marked "TOOL RECOVERY". The tool automatically retraces its movement over the path made manually and returns to its original position. (4) When cycle start is initiated, operation resumes at the exact position where it was suspended.

High-Speed M/S/T/B Interface
The communication of execution command signal and completion signal in M/S/T/B function were simplified to realize a high-speed execution of M/S/T/B function.

Easy Operation Enables The Elimination of Time Consuming Machine Setup Chores
The tool offset value (tool length) can be easily measured simply by feeding the tool manually until it comes to rest against the machine's touch sensor or base block. Similarly, the workpiece zero offset value can be measured by feeding the tool manually and bringing it to rest against the surface of the workpiece.
In machining center and milling machine applications, in addition to the workpiece surface it is also possible to measure the work piece zero offset value for both the X axis and Y axis so that the hole's center is the workpiece zero point, simply by manually feeding the touch probe over three points in the hole.
In addition to measurement by manual feed, it is also possible to measure the tool offset value (tool length) automatically using program commands.
Electronic Absolute Position Dectector Need for Reference Point After Power Restoration
All systems feature a fully electronic absolute position detector which retains the exact machine position even in the event of a power shutdown. This enables immediate resumption of automatic operation after power restoration.

Large Tape Memory
A large-capacity tape memory has been provided to facilitate NC part program managernt The GE Fanuc Series 11 and 12 adopt state-of-the-art 4Mbit bubble memories as the storage elements

Background Editing
While machining is in progress, it is possible to edit the program for the next machining process. The ability to perform simultaneous machining and program preparation enables maximum efficiency in system use.

A Host of Easy to use Features Result in More Effective Machining

Simultaneous Automatic/Manual Operation
Automatic and manual operation can be performed simultaneously. For example, it is possible to manually change the cutting value for an axis which is cutting under automatic operation, or to per form setup procedures for the next work piece while automatic operation is under way. In addition it is possible to achieve applications such as use of a single lathe to simultaneously perform turning and drilling

Polar Coordinate Interpolation
This feature is ideal for cam grinding and face milling (X. C axis) using a lathe. The machining profile can be programmed using an orthogonal coordinate system. Cutter radius compensation can also be carried out simply by commanding G41 or G42. Thereafter, movement of the linear axis (X axis) and rotary axis (C axis) is converted in the NC.

Cylindrical Interpolation
This feature is ideally suited to cylindrical groove cutting needs. Programming can be performed precisely as the cylinder is developed.
Cutter radius compensation is also carried out simply using the G41 or G42 command. The NC converts this information into rotary axis movement based on the cylinder radius as instructed

Polygon Machining
Polygon machining is a method of machining whereby polygonal shapes are achieved by rotating the workpiece and a tool at a fixed ratio. The result – tetragon, hexagon, etc. - varies according to two machining conditions:
(1) the rotation ratio between the workpiece and the tool, and (2) the number of tool cutters. Because it is impossible to achieve a perfect polygon, machining of this type is generally suited to applications such as square or hexagonal bolt heads and hexagonal nuts.
(Example) Workpiece/tool rotation ratio: 1:2 3 cutters at 120° intervals: hexagon

Detachment of Control Axis
NC control axes can be temporarily released from control when necessary. When the rotary table is being attached or detached, or when the servo motor is connected to the spindle (C-axis) to perform contour cutting with another axis in lathe applications, this feature enables the servo motor to be detached from the spindle and substituted by the spindle motor during turning operations.

Turret Axis Control
Turret indexing can be controlled by servo motor using one of the NC's control axis. This enables turret indexing to be carried out simultaneous with the movement of the other axis.
During automatic operation, turret indexing is executed using T commands. During manual operation, the nearest tool is selected when feed is halted.

Automatic Corner Override
With this feature, the feed rate is automatically lowered when cutting inner corners in the cutter compensation mode. This prevents over loading of the cutter at the corner, for smoother cutting surfaces.

Direct Drawing Dimension Programming
The angle of straight line, chamfering value, corner radius value, etc. indicated on the machining drawing can be used directly in programming. Further, it is possible to insert chamfering and corner rounding between straight lines at an arbitrary angle.

Figure Copy
This function simplifies programming tasks hen the machining profile contains the same pattern in repetition. Rotation and parallel copy modes are possible.

Axis Interchange
This feature enables switching to the x-, y- or z-axis of the machine in accordance with the X/Y/Z axis address commands in the program.

Tool Offset by Tool Number
The tool length offset value, cutter radius off.
Set value and magazine pot number can all be set for various tool numbers. When the tool number is instructed, the pot number for the corresponding tool is notified to the machine.

Tool Life Management
Tools can be classified into various groups, and the tool life and tool numbers for each group can be arranged in the NC memory in the form of a table. In the event that a certain tool in a group reaches its life while machining is in progress, it is automatically replaced by another tool in the same group which is still useful. This feature enables automation of tool life management and thereby can be of great assistance in achieving full Factory Automation.

Index Table Control
Indexing of the index table, which is indispensible for the performance of multi-surface machining, can be controlled using one axis of the NC

Multiple Repetitive Cycles
These cycles feature generates a series of cutting path with simple tape commands. For instance, the data of the finishing work shape decides the tool path for rough cutting automatically

Double Check System
It checks for any discrepancy between the two. This system prevents expensive workpieces from being incorrectly cut.
Servo feedback signals during cutting, and stops cutting when the discrepancy is larger than the specified value.

Three-Dimensional Tool Offset
In machining a curved surface, offset by an offset value set in a 3-dimensional direction is provided. The offset direction is given as a vector with I, J, K together with X, Y, Z by a programmed command.

Hybrid Servo Control
With this feature, the semi closed loop and closed loop are mixed to substantially raise servo gain. Up to 15 axes are possible. This function allows rapid driving of a large machine tool.

NC/TC Function
When furnished with the NC/TC function, one controller can execute the functions previously requiring two controllers (NC and TC). The machining method most suited to a profile can be selected for efficient die shaping.
Tracing: for 3-dimensional machining requiring difficult tape preparation.
NC machining: for high-precision 2-and 3-dimensional shaping.
Combined use of NC and tracing: for contours with convex and concave bottom surfaces or complex grooves, which are difficult to machine only with a single NC or tracing functions.
Digitizing function is available, to pick up tracing data and store into memory.

High Reliability and Easy Maintenance Proven over the Years

Significantly Fewer Component Parts
The number of required component parts has been dramatically reduced through the adoption of today's most advanced 4Mbit bubble memories and 8,000-gate custom LSI. The result is a substantial improvement in overall reliability.

Simplified Interconnections by Optical Fiber
A single optical fiber may be used to connect the control unit with the NC operator's panel or with the I/O unit, thus greatly simplifying connections between machines. Optical fiber also makes for sharply improved protection against noise.

Dustproof MIDI Keyboard
The MDI keyboard features a totally sealed structure completely covered with an oil resistant sheet. The surface sheet is made of a highly resilient material shaped to match the configurations of each key. So key-in operations are easier to perform than with conventional sheetkeys.

Long Life I/O interfaces
I/O cards, connection units and I/O units are offered as interfaces with the magnetics cabinet. All interfaces, including AC type, feature solid state technology for a long service life. Especially, nonpolarized DC outputs are easy to interface with magnetics control.

Easy-to-maintain Turnkey System
Use of I/O units permit the elimination of relays, connector panels and terminal boards. This enables the creation of a full turnkey system contained in a single cabinet including the NC, resulting in easier maintenance and lower system costs.

Stringently Controlled PMC Cassettes
Debugged programs can be written onto PMC cassettes. PMC cassettes are rigidly screened before shipment. A special ROM writer (Fanuc PMC WRITER) carefully controls the writing procedure, so high reliability is guaranteed. The machine manufacturer can therefore perform write-in tasks with complete confidence.

Self-diagnostic Functions
A self-diagnostic features provide constant monitoring of the inside of the CNC. In the event of malfunction, operation is automatically halted immediately and the state of the map function is displayed.
Feedback pulses from the position detector are monitored at all times. Detector failures or intermittent failures due to noise are detected immediately.
