PREPARATION

The following preparation is needed in order to use this multi-path

lathe application.

NOTE

When using the path selection soft key of Manual

Guide i, make a setting so that the reset key on the

MDI panel is enabled for all paths (bit 0 of

parameter No. 8100 is 0).

(If the reset key is enabled on a path-by-path basis,

(bit 0 of parameter No. 8100 is 1), the path

selected in the NC is reset regardless of which path

is selected in Manual Guide i.)

Changing Screens for Each Path

On the MANUAL GUIDE i for multi-path lathe, screens and

operations are done on each path respectively.

On its screen, the icon for selected path will be displayed at the upper

right part.

1.2.1.1 Changing by a soft-key

On the each screen, CHPATH soft-key will be displayed.

Press [CHPATH], the displayed turret will be changed.

In case of 2-path system : turret-1 > turret-2 > turret-1 > …

In case of 3-path system : turret-1 > turret-2 > turret-3 > turret-1 > …

ANIMATION FOR MULTI-PATH LATHE

The tool path and animation for multi-path lathe are available.

NOTE

1 When machining simulation is started, it is

necessary to set MEM mode for all path.

2 Displaying is not done for the combination where

the parameter is set to the combination of the main

axis and the cutlery stand as invalidity.

Tool Path Drawing During Machining and Tool Path

Machining Simulation

In the tool path drawing during machining (tool path), machining

simulation (tool path), the turret selected now is drawn.

When the path (turret) is changed during drawing, the drawing starts

from halfway status.

When the mode of changed path (turret) is other of MEM mode, the

drawing will stop.

1.4

MACHINING SIMULATION FOR EACH PATH

In the multi-path system of MANUAL GUIDE i, the machining

simulation is performed only at the selected path by the R signal.

In the multi-path system of MANUAL GUIDE i, the machining

simulation is performed only at the selected path by a R signal that is

set at the parameter No.27309 (The first figure is “bit” and the other

figure is the R signal number.).

For example, with 2 paths system

- At Path 1, the parameter No.27309=1001

- At Path 2, the parameter No.27309=2001

Then,

- At Path 1, if R100.1 is 1

- At Path 2, if R200.1 is 1

machining simulation is performed at each path. The status of the

signal of each path is displayed at a title bar of simulation window.

Green is the status for enable the simulation to be performed. Gray is

the status for disable.

Ex.1 With 2 paths system, the signal of Path 1 is 0 and the one of

Path 2 is 1.

Ex.2 With 3 paths system, the signal of Path 1 is 0 and the ones of

Path 2/3 are 1.

1.MULTI-PATH LATHE APPLICATION MULTI-PATH LATHE FUNCTIONS

B-63874EN/04

NOTE

If M code for waiting other paths is commanded,

the machining simulation is in pausing for

performing of the same M code at other paths. So,

if this function is made available in use of M code

for waiting, it must be made disabled by the

management such as the M code is disabled by

using a signal of PMC for ignoring it.

This function needs the optional function MANUAL

GUIDE i Animated Drawing.

In drawing during machining, R signal that is set at

the parameter No. 27309 is disabled.

If the parameter No.27309 is not set at any paths,

this function is disabled.

R signal, which is set at the parameter No. 27309,

is available in converting into NC formatted

program, too. The NC statement converting

function is available only at the path in displaying.

So, when the R signal at the path, which is the

object for NC statement converting, is off, the

warning message “TURN THIS PATH'S

SIMULATE-SWITCH ON” is displayed.

In the NC statement converting function, the status

of the R signal is not displayed.

Even if the R signal of a path is turned from “ON“ to

“OFF” in the machining simulation, the machining

simulation is not pausing but is performed at the

path.

Even if the R signal of a path is turned from “ON“ to

“OFF” in the machining simulation, [SINGLE] and

[PAUSE] are not available at the path. In short,

these soft keys are available at the path when the

R signal is on.

If [STOP] or the RESET is pressed in the

machining simulation, it stops at all paths for all

status of the R signal.

10 If any paths are in machining, the machining

simulation can not be performed.

11 To perform the machining simulation, the mode

must be MEM at the selected path for displaying. If

it is turned to another path in the other mode than

MEM in the machining simulation, the machining

simulation is stopped and the animation window

turns off.
