Introduction

This manual describes the specifications of CNC C70. To safely use this CNC module, thoroughly study the "Precautions for Safety" on the next page before use.

Details described in this manual

At the beginning of each item, a table indicating it's specification according to the model.

CAUTION

The items that are not described in this manual must be interpreted as "not possible". This manual is written on the assumption that all option functions are added. Some functions may differ or some functions may not be usable depending on the NC system

(software) version.

General precautions

(1) When the contents of this manual is updated, the version (A, B, …) on the cover will be incremented. (2) In this manual, the machining center system is described as "M system" and the lathe system is described

as "L system".

Precautions for Safety

Always read the specifications issued by the machine maker, this manual, related manuals and attached documents before installation, operation, programming, maintenance or inspection to ensure correct use. Understand this numerical controller, safety items and cautions before using the unit. This manual ranks the safety precautions into "Danger", "Warning" and "Caution".

DANGER

When there is a great risk that the user could be subject to fatalities or serious injuries if handling is mistaken.

WARNING

CAUTION

When the user could be subject to fatalities or serious injuries if handling is mistaken.

When the user could be subject to injuries or when physical damage could occur if handling is mistaken.

Note that even items ranked as "

CAUTION

", may lead to major results depending on the situation. In any

case, important information that must always be observed is described.

DANGER

Not applicable in this manual.

WARNING

Not applicable in this manual.

CAUTION

1. Items related to product and manual

(software) version.

2. Items related to start up and maintenance

Follow the power specifications (input voltage range, frequency range, momentary power failure

time range) described in this manual.

Follow the environment conditions (ambient temperature, humidity, vibration, atmosphere)

described in this manual.

If the parameter is used to set the temperature rise detection function to invalid, overheating

may occur, thereby disabling control and possibly resulting in the axes running out of control, which in turn may result in machine damage and/or bodily injury or destruction of the unit. It is for this reason that the detection function is normally left "valid" for operation.

1.1 Control Axes

1. Control Axes

The NC axis, spindle, PLC axis are generically called the control axis. The NC axis is an axis that can be manually operated, or automatically operated with the machining program. The PLC axis is an axis that can be controlled from the PLC ladder.

1.1 Control Axes

1.1.1 Number of Basic Control Axes (NC axes)

M system : { 3 axes L system : { 3 axes

1.1.2 Max. Number of Control Axes (NC axes + Spindles + PLC axes)

A number of axes that are within the maximum number of control axes, and that does not exceed the maximum number given for the NC axis, spindle and PLC axis can be used. For example, if 16 NC axes are used, this alone is the maximum number of control axes, so a spindle and PLC axis cannot be connected.

2.4.1 Decimal Point Input I, II

M system : { L system : {

There are two types of the decimal point input commands and they can be selected by parameter. (1) Decimal point input type I (When parameter #1078 Decpt2 is 0.)

When axis coordinates and other data are supplied in machining program commands, the assignment of the program data can be simplified by using the decimal point input. The minimum digit of a command not using a decimal point is the same as the least command increment. Usable addresses can be applied not only to axis coordinate values but also to spee d commands and dwell commands. The decimal point position serves as the millimeter unit in the metric mode, as the inch unit in the inch mode and as the second unit in a time designation of dwell command.

(2) Decimal point input type II (When parameter #1078 Decpt2 is 1.)

As opposed to type I, when there is no decimal point, the final digit serves as the millimeter unit in the metric mode, as the inch unit in the inch mode and as the second unit in the time designation. The "." (point) must be added when commands below the decimal point are required.

2.4.2 Absolute/Incremental Command

M system : { L system : {

(1) M system

When axis coordinate data is issued in a machining program command, either the incremental command method (G91) that commands a relative distance from the current position or the absolute command method (G90) that moves to a designated position in a predetermined coordinate system can be selected. The absolute and incremental commands can be both used in one block, and ar e switched with G90 or G91. However, the arc radius designation (R) and arc center designation (I, J, K) always use incremental designations. G90 ... Absolute command (absolute value command) G91 ... Incremental command (incremental value command) These G codes can be commanded multiple times in one block.

Example

Absolute value Incremental value Absolute value

(2) L system

When axis coordinate data is issued in a machining program command, either the incremental command method that commands a relative distance from the current position or the absolute command method that moves to a designated position in a predetermined coordinate syste m can be selected. When issuing an incremental value command, the axis address to be commanded as the incremental axis name is registered in the parameter. However, the arc radius designation (R) and arc center designation (I, J, K) always use incremental designations. Absolute command (absolute value command) ...

2.4.3 Diameter/Radius Designation

M system : - L system : {

For axis command value, the radius designation or diameter designation can be chan ged over with parameters. When the diameter designation is selected, the scale of the length of the selected axis is doubled. (Only the half (1/2) of the commanded amount moves.) This function is used when programming the workpiece dimensions on a lathe as diameters. Changing over from the diameter designation to the radius designation or vice versa can be set separately for each axis.

The above command positions the tool by rapid traverse. The tool path takes the shortest distance to the end point in the form of a straight line. For details on the rapid traverse feed rate of the NC, refer to the section entitled "Rapid Traverse Rate". Since the actual rapid traverse feed rate depends on the machine, refer to the specifications of the machine concerned.

(1) The rapid traverse feed rate for each axis can be set independently with parameters. (2) The number of axes which can be driven simultaneously depends on the specifications (number of

simultaneously controlled axes). The axes can be used in any combination within this range.

(3) The feed rate is controlled within the range that it does not exceed the rapid traverse rate of each axis

and so that the shortest time is taken. (Linear type) Parameter setting enables movement at the rapid traverse rates of the respective axes independently for each axis. In this case, the tool path does not take the form of a straight line to the end point. (NonLinear type)

G code Function

G96 Constant surface speed G97 Constant surface speed cancel

The surface speed is commanded with an S code. For the metric designation, the speed is commanded with an m/min unit, and for the inch designation, the speed is commanded with a feet/min unit. In the constant surface speed cancel mode, the S code is a spindle rotation speed command. The axis for which constant surface speed is controlled is generally the X axis. However, this can be changed with the parameter settings or with address P in the G96 block.

(Note 1) If there is only one spindle, the spindle will not operate normally if the constant surface speed

control command, S command or spindle related M command is commanded randomly from each part system. These commands must be commanded from only one certain part system, or commanded simultaneously with standby. The controller will execute the following control for the constant surface speed control and S commands. The part system from which an S command was issued last will have the spindle control rights. That part system will judge whether the constant surface speed co mmand mode is

8.1.6 Spindle Orientation

M system : { L system : {

(1) Orientation

This function stops the spindle rotation at a certain position when using the digital spindle. When the orientation command is used, the spindle will rotate several times and then stop at the orientation point. The orientation point is the Z-phase position when using encoder orientation (PLG and external encoder) or the proximity switch neighborhood when using the proximity switch method.

(2) Multi-point orientation

This function performs orientation to a position other than the Z-phase position by inputting a shift amount with the parameter or PLC. The shift amount is 0 to 35999. (Unit: 360°/36000 = 0.01°)

(Note 1) Orientation is possible only when the gear ratio is 1:1 for the PLG orient.

(The orientation is completed at the PLG encoder's Z-phase, so when using reduction gears, the orientation points will be generated at several points during one spindle rotation.)

8.1.8.1 Spindle Synchronization I M system : Δ L system : Δ

In a machine with two or more spindles, this function controls the rotation speed and phase of o ne selected spindle (synchronized spindle) in synchronization with the rotation of the other selected spindle (basic spindle). It is used in cases where, for instance, workpiece clamped to the basic spindle i s to be clamped to the synchronized spindle instead or where the spindle rotation speed is to be changed while one workpiece remains clamped to both spindles.

The synchronous spindle is designated and the start/end of the synchronization are commanded with the G command in the machining program.

9.3.2.1 Tool Shape/Wear Offset Amount M system : { L system : {

This function registers the tool shape offset and wear offset amounts among the positions of the tools moving in the direction parallel to the control axis. Compensation may encompass two or more axes. (1) Shape offset amount

The tool length offset amount, tool radius compensation amount, nose radius compensation amount, nose radius imaginary tool tip point or tool width can be set as the shape offset amount. The compensation amount that can be set and used differs depending on whether offset amount setting type 1, 2 or 3 is used.

(2) Wear offset amount

When the tip of the tool used has become worn, the wear offset amount is used to offset this wear. Types of wear offset amounts include the tool length wear offset amount, tool radius wear compensation amount, and nose radius wear compensation amount. The wear offset amount can be used with offset amount setting types 2 and 3, and it is added to the shape offset amount for compensation.

(a) Type 1: 1-axis offset amount [M system]

This is the value that is used by rotary tools. As the tool length offset amount, among the offset amounts for the position of the tool moving in the direction parallel to the control axis, the offset amount in the longitudinal direction of the rotary tool is registered. The tool length offset amount is set as a minus value. As the tool radius compensation amount, among the offset amounts for the position of the tool moving in the direction parallel to the control axis, the offset amount in the radial direction of the rotary tool is registered. The tool radius compensation amount is set as a plus value. One offset amount data is registered in one offset number, and the offset Nos. are assigned using the address D or H commands. When a No. is assigned by a D a ddress command, offset is provided in the form of the tool radius; when it is assigned by an H address command, it is provided in the form of the tool length.

(b) Type 2: 1-axis offset amounts/with wear offset [M system]

As with type 1, type 2 is for the offset amounts used by rotary tools. With type 2, four kinds of offset amount data are registered in one offset No.: the tool length offset amount, tool length wear offset amount, tool radius compensation amount, and tool radius wear compensation amount. When an offset No. is assigned by address D as the offset amount, the tool radius is compensated using the amount obtained by adding the tool radius compensation amount and tool radius wear compensation amount. Further, the tool length is offset using the amount obtained by adding the tool length offset amount and tool length wear offset amount.

Type 3 is for the offset amounts used by non-rotary tools.

Offset is provided in the directions of the X, Z axes and additional axis from the base position in the program.

In addition to the six workpiece coordinate systems G54 to G59, 48 workpiece coordi nate systems can be used by assigning G54.1Pn command. The command format to select the workpiece coordinate system using the G54.1Pn command and to move on the workpiece coordinate system are given below.

(G90) G54.1Pn G00 Xx1 Yy1 Zz1 ;

G90 G54.1Pn G00 Xx1, Yy1, Zz1

The numerical value n of P following G54.1 indicates each workpiece coordinate system. Specify a value between 1 and 48.

The workpiece coordinate zero points are provided as distances fro m the zero point of the machine coordinate system. Settings can be performed in one of the following three ways:

(a) Setting using the setting and display unit (b) Setting using commands assigned from the machining program (c) Setting from the user PLC

10.1.5 External Workpiece Coordinate Offset

M system : { L system : {

External workpiece coordinate offset that serves as the reference for all the workpiece coordinate systems is available outside the workpiece coordinates. By setting the external workpiece coordinate offset, the external workpiece coordinate system can be shifted from the machine coordinate system, and all the workpiece coordinate systems can be simultaneously shifted by an amount equivalent to the offset. When the external workpiece coordinate offset is zero, the external workpiece coordinate systems coincide with the machine coordinate system. It is not possible to assign movement commands by selecting the external workpiece coordinates.
