G00 / G100 G00, G100 Non-productive fast speed linear interpolation.

Description Optimizes unproductive motions.

At first the system determines the highest possible traversing rate between the axis start and end points. If however the axis reaches its end point too soon, it will have to stand by for action. If so, the system recomputes the rate down, which brings the axis to its end point a little later, i.e. right before it is required to move into action again.

L = Chamfer Length for positive value (facultative)

L-= Chamfer Length / 1.414 for negative value (facultative)

E = Tool path velocity for chamfer expressed in active units (facultative)

Description These functions are used to link two non-parallel segments/stops, by another segment or circle arc.

It is not possible to link 2 segments of 2 different operations by a chamfer.

Note :

Settings programmed under L are saved for G26 and G27 separately. L-Parameter is facultative and unless you specify it, G26/G27 will take over its last own setting entered. If none was entered, G26 will take over the default setting from Default Radius Box and G27 from ChamferLength Box in the Global section of the machine database.

The last setting entered with E is saved and remains identical for G26 and G27. E-Parameter is facultative and unless you specify it, G26/G27 will take its last own setting entered. If none was entered, G26/G27 will take the last velocity setting entered for the segments.

The chamfer is perpendicular to the bisecting line of the angle formed by the two chamfer-linked segments.

Note :

G28 runs always at 100% feedrate.

DECO, MultiDECO :

G28 is used only when the actual position of the axis is unknown.

A dwell must be programmed after G28 block to let the axis return to its reference point, before to command the next movement.

Sigma, MultiAlpha :

On ISO-programming machines, G28 is interpreted as follows :

For example, G28 X12 is converted into G91 G28 X12=0 G90 in the CNC (*.dnc file). Warning!

DECO, MultiDECO :

Make absolutely sure to enter G28 in the INIT program only, because only here the actual position of the axis is unknown.

DECO, MultiDECO, MultiAlpha :

Collision risk : If none axis is specified, all axes in the Operations-line, returns at the same time to their reference position!

In the other programs (first of all Main Program Nr.2), use System Variables #24, #25, #26 to reference the axes. (See Description of System Variables).

Sigma :

If none axis is specified, the G28 command is ignored.

G92 G92 limits the maximum spindle speed.

Sphere of application This function is applied to the use of the G96 function.

Description G92 limits the maximum spindle speed to a value less than that of the machine database.

Note This function is used before the G96 function, if it is necessary to limit the maximum spindle speed.

Use Syntax:

G92 Sxxxx

S: Maximum authorised speed in turn/min of the spindle in G96 mode. This speed must be less than the machine

database value. If the value is negative, the maximum speed in Mx04 is used. S is automatically displayed after entering G92. (xxxx is the numeric value of this speed).

The maximum spindle speed S is automatically limited to the one contained in the machine database. If it is exceeded, a message is displayed, then the speed is reduced to the value contained in the machine database.

Use For the PNC-DECO control all axes are independent of each other: For this reason spindle speeds are in no way related to feedrates.

Feedrates [mm/rev] are controlled according to the programmed spindle speeds and converted then to [mm/min].

The programmed feedrate [mm/rev] is real on the machine only when the spindle and axis overrides are identical, usually 100% by default.

Feedrate [mm/rev] is disregarded when :

overriding axis feedrate only, i.e. axis feedrate changes while spindle speed does not.

overriding spindle speed only, i.e. spindle speed changes while axis feedrate does not.

To avoid problems with relating spindle speeds to the calculation of feedrates [mm/rev], set up the program as follows :

S1 in Operation Line of Comb-Gang 1

S2 in Operation Line of Comb-Gang 2

S3 in Operation Line of Frontwork Gang

S4 in Operation Line of Backwork Gangs

of 38G-Code Table


COMPUTING FEEDRATE [mm/rev] in G95

If no spindle speed is programmed in the operation, the last speed entered in Operation Line will be taken for the feedrate calculation. The calculated feedrate is correct.

Spindle speed change in the operation. The programmed spindle speed is related to the axes in Operation Line. The feedrate calculation is correct.

S1-spindle speed change. The programmed spindle speed is related to the axes in Operation Line. The feedrate calculation is correct.

S3-spindle speed change. The programmed spindle speed is not related to the axes in Operation Line. The feedrate calculation is incorrect. S3 speed will be at 10000 rpm but the feedrate will be calculated with 5000 rpm.

G96 / G97 G96 Constant cut-off speed [m/min].

G97 (or Mxyy) Cancel G96

Sphere of application To obtain optimum cutting conditions when turning, a different rotation speed is needed for each diameter variation. The constant cut-off speed function effects this calculation automatically.

When cutting off or facing large diameters, this function is used to decrease the required machining time and to have a regular surface finish and better quality.

Syntax G96 Sxxxx P1=cc

S: The constant cut-off speed in [m/min or feet/min]. If the value is negative, the spindle turns in Mx04. S is automatically displayed after entering G96.

P1: Axe where the G96 function is to be applied. This parameter is optional. If it is not programmed, axis X of the operation line is selected by default.

(For example: If you want to apply G96 on axis Y of Chaser 1, write P1=Y1).

Description The “constant speed function” changes the spindle rotation speed based on the position of axis X, in order to obtain optimal cut-off conditions.

Each time the axis is moved, the function G96 recalculates the spindle rotation speed based on the desired constant cut-off speed, and the new position of the axis.

The feed of the axis segment is recalculated based on this new spindle speed.

Use The G96 function can be used various times on the same spindle, only the first G96 requires the speed parameter S, the user can delete it for the subsequent G96 functions. TB-DECO will then take the value S by default, which is specified in the previous G96 function, associated to the same spindle.

Note If the feed is programmed in [mm/turn] (G95), it is recalculated with each variation of the spindle speed.

If the feed is programmed in [mm/m] in (G94), it is fixed and only the spindle speed can vary.

The operation line must contain a direction X-axis or the axis specified by the parameter P1 of G96. If this is not the case, the code G96 is ignored and a warning is displayed.

If the line contains various axes with the same name (xx or yy) and the parameter P1 has not been set, then an alarm is generated.

Cancel : G97 or Mxyy G97 or Mxyy (Sxxxx). cancels the G96 function

Syntax 1

G97 Sxxxx

S: New spindle speed in [turn/min.] This parameter is optional. If it is not present, the spindle speed remains the one calculated in G96.

S is not automatically displayed after entering G97.

Syntax 2

Mx03 Sxxxx, Mx04 Sxxxx, or Mx05

X : Spindle number.

03 : Clockwise rotation, 04 : Anti-clockwise rotation, 05 spindle stop.

S: New spindle speed in [turn/min]. (xxxx is the numeric value of this speed).

Note:

The G96 mode remains enabled as long as G97 or a spindle speed-up function has not been enabled, even if the operation is changed.

The operation line containing G96 determines which spindle and axis are used (X by default, if P1 is not specified).

If G96 is programmed in an operation of chaser 2 (line Z1 X2 Y2 and spindle S1), the spindle S1 becomes dependent on axis X2.
