When automatic operation is to be performed, each tool post is activated

after selecting a program for machining with tool post 1 and a program

for machining with tool post 2 from the programs stored in program

memory for each tool post. Then the programs selected for the tool posts

are executed independently at the same time. When tool post 1 and tool

post 2 need to wait for each other during machining, the waiting function

is available (Section 20.2)

Just one MDI is provided for the two tool posts. Before operation and

display on the MDI, the tool post selection signal is used to switch

between the two tool posts.

WAITING FOR TOOL

POSTS

Explanations

Control based on M codes is used to cause one tool post to wait for the

other during machining. By specifying an M code in a machining

program for each tool post, the two tool posts can wait for each other at

a specified block. When an M code for waiting is specified in a block for

one tool post during automatic operation, the other tool post waits for the

same M code to be specified before staring the execution of the next block.

This function is called the tool post waiting function.

A range of M codes used as M codes for waiting is to be set in the

parameters (Nos. 8110 and 8111) before hand.

Example

M100 to M103 are used as M codes for waiting.

Parameter setting: No. 8110= 100 (Minimum M code for waiting:

M100)

No. 8111= 103 (Maximum M code for waiting:

TOOL POST

INTERFACE CHECK

20.3.1

When two tool posts machine the same workpiece simultaneously, the

tool posts can approach each other very closely. If the two tool posts

General

interfere with each other due to a program error or any other setting error,

a serious damage such as a tool or machine destruction can occur.

The function “tool post interference check” is available which can

decelerate and stop the two tool posts before the tool posts interfere with

each other due to an incorrect command.

Tool post 2

Tool post 1

The contours of the two tool posts are checked to determine whether or

not an interference occurs.

To make a tool post interference check, data including the relationships

20.3.2

between the two tool posts and interference forbidden areas (that is, tool

Data Setting for the

shapes) needs to be set. The method of such data setting is described

Tool Post Interference

below.

Check Function

With the tool post interference check function, whether or not the two tool

posts interfere with each other is determined by checking if the

interference forbidden areas (based on the interference forbidden areas of

the currently selected tools) of the tool posts overlap each other after the

movement of the tool posts.

(2) After power is turned on, reference point return operation is completed

with all axes (X1, Z1, X2, Z2). (When an absolute-position detector

is used, the matching between a machine position and

20.3.5

when all conditions described in Section 20.3.4 are satisfied, a tool post

Execution of Tool Post

an interference forbidden area is set for the two tool posts by using the tool

Interference Checking

shape data corresponding to the currently selected tool numbers.

Then whether the areas interfere with each other is checked.

Explanations

Tool post 1

Tool post 2

When interface forbidden areas (tool shapes) as indicated by dashed lines

are set for tool posts 1 and 2 as shown above, a check is made by

determining whether the two interference forbidden areas indicated by

dashed lines overlap each other after the movement of the tool posts.

If the two areas interfere with each other an P/S alarm (No. 508 or No. 509)

is raised;the two tool posts are decelerated and stopped.

If an interference alarm is raised, a tool post interference alarm signal is

output to the PMC.

If an interference alarm is raised by the interference of the two tool posts

during automatic operation, switch to manual mode to move the tool posts

out of the interference state. Then release the alarm by a reset.

The interference check function can be enabled even in manual mode by

setting the parameter (No. 8140#3) to 1. This allows the tool posts

interfering with each other to be moved along the axes only in such

directions that clear the interference. With this capability, the two tool

posts interfering with each other in automatic operation cannot be

manually moved by mistake further into the interference forbidden areas

after the mode is switched to manual mode to clear the interference, thus

providing safety.

408

20. TWO-PATH CONTROL

B-63524EN/01

PROGRAMMING

FUNCTION

WARNING

When an alarm is raised, the CNC system and machine

system stop with some delay in time.

So an actual stop position can be closer to the other tool

post beyond an interference forbidden position specified

using tool shape data. So, for safety, tool shape data a little

larger than the actual shape should be set. The extra

distance, L, required for this purpose is calculated form a

rapid traverse feedrate as follows

1

L= (Rapid traverse feedrate) ×

7500

For example, when a rapid traverse feedrate of 15 m/min is

used, L=2mm.

CAUTION

When parameters and interface forbidden areas are set to

use the interference check function, be sure to check that

correct interference forbidden areas are set. For this

purpose, set manual mode, and cause the tool posts to

interfere with each other in various directions.

When a thin workpiece is to be machined as shown below, a precision

20.4

machining can be achieved by machining each side of the workpiece with

BALANCE CUT

a tool simultaneously;this function can prevent the workpiece from

(G68, G69)

warpage that can result when only one side is machined at a time. When

both sides are machined at the same time, the movement of one tool must

be in phase with that of the other tool. Otherwise, the workpiece can

vibrate, resulting in poor machining. With this function, the movement

of one tool post can be easily synchronized with that of the other tool post.

Fig. 20.4 Balance cut

Explanations

When G68 is specified in the programs for both tool post 1 and tool post

2, the pulse distribution of tool post 1 is synchronized with that of tool

post 2 to start balance cutting. Thus the two tool posts can move exactly

at the same time to allow balance cutting.

In the balance cut mode, balance cutting is performed only when a move

command is specified for both tool posts. Balance cutting is performed

even when different axes are specified for each tool post or an offset move

command is specified. G68 or G69 must be specified in a single block.

(Otherwise, a P/S alarm (No. 163) is raised. When G68 or G69 is

specified with one tool post, the tool post does not move until the

execution for the other tool post proceeds to G68 or G69. And if cutting

is specified with one tool post in the balance cut mode, the tool post does

not move until the execution of or the other tool post proceeds to a cutting

command.

CAUTION

Balance cut only starts cutting feed on both tool posts at the

same time; it does not maintain synchronization thereafter.

To synchronize all the movements of both tool posts, the

setting for both tool posts, such as the travel distance and

feedrate, must be the same.

HOLE PATTERN :

This is the menu title. An arbitrary character string consisting of up

to 12 characters can be specified.

BOLT HOLE :

This is the pattern name. An arbitrary character string consisting of

up to 10 characters can be specified, including katakana.

The machine tool builder should specify the character strings for the menu

title and pattern name using the custom macro, and load the character

strings into program memory as a subprogram of program No. 9500.

The selected pattern No. is assigned to system variable #5900. The

custom macro of the selected pattern can be started by starting a fixed

program (external program No. search) with an external signal then

referring to the system variable #5900 in the program.
