Before initial operation read these instructions thoroughly, and retain for future reference.

YASUAWA

Specification upgrading of several functions is possible witn YASNAC LX3 if it has a “Compact Interactive Function. ” (optional).

This manual describes these specification upgrading items and

operation.

The reader is requested to refer to the YASNAC LX3 Operator’s Instruction Manual (TOE-C843-9.20) regarding those items that are not covered here.

The data No. of the operator’s manual referred

to in this manual is ‘TOE-C843-9.20.

Nose R compensation can be executsd with the G 70 to G 73 cycles even while the finish profile program is being performed.

By this, G41 and G42 are added to the G codes that can be designated by the blocks other than blocks Ns f and Nnf during finish profile program execution. During the rough finish and finish cycles, nose R compensation will become effective during the finish cycle by the blocks instructed by G41 to G42.

Always instruct with the GOO or GO 1 moving command when instructing G41/G42 to the block to start the finish profile program.

Commands with single-blocks are prohibited.

Precautions in Upgrading of Multiple Canned Cycle Function

The following conditions are added to pars. 1.1.1, 1.1.2 and 1.1.3.

This upgrading increases the maximum memory capacity of the finish

(b)

profile programs to 39 blocks.

Change in (2) of par.2.8.25.l in the YASNAC LX3 Operator’s Manual.

(2)

Precautions to G74/G75 upgrading in par.1.5. If neither Command A nor Corr.mand B is given, the execution will be

(a)

the same as in previous G74/G’75. If Command B only is given, blade width shifting is executed at the

(b)

beginnj.ng and end of G74/G75 as mentioned in detail below:

(i) The first motion is shifting by the blade width in the X-axis co:m-

ma.nd direction with G74 and in the Z-axis command direction with

G75 from the position of the block immediately before G74/G75.

(ii) The last motion is returning to the position of the block immedi-

ately before G74/G75 after being shifted by the blade width

amount.

If Command A only is given, o:dy retract is executed without executing

(c)

blade width shifting. If Command A is given, the pull back amount with G74 and G75 will be

the set amount of # 6208 and 6209.

2. NEW TOOL SETTER FUNCTION

2.1 GENERAL

Offset amounts and work coordinate system shift amounts can be written automatically by manual operation even if the machine is not equipped with a touch sensor.

This function simplifies setup during tool change. This function differs from the previous tool setter function with a touch

sensor in tool coordinate memory value and in work coordinate shift amount.

The previous tool coordinate memory data was the differential distance value between the touch sensor and the tip of the selected tool. This has been changed to the differential distance value between the workpiece end face and the tip of the tool. been changed the shift amount from the projected home position to that from the workpiece end face.

However, function is called the new tool setter function.

the approach to the coordinate system does not change. This

2.2 WRITING TOOL COORDINATE MEMORY

Regardless of whether or not a measuring tool for a setter in the machine exists, the tool coordinate memory amount can be written by manual operation as follows.

The tool coordinate memory amounts written in this case will be the differential distance value between the workpiece end face and the tip position of the applicable tool.

The work coordinate system shift amount has
