EXPLANATORY NOTES

WARNING

All data described in this Part such as parameter,

offset data and part program cannot be used for

actual machining. Actual data varies from one

machine model to another. Refer to the applicable

manual supplied by the respective machine tool

builders for details.

If the set data does not match the characteristic of a

specific machine, the tool may bump against the

workpiece, and the machine may be forced to

perform unnatural machining, possibly causing

damage to the tool and/or machine, and even

injuries.

The part program made by using MANUAL GUIDE i has a form of

ISO-code program with G-code and so on.

You must enter the program used for such as tool changing, tool offset,

spindle rotation, approaching and releasing in the form of ISO-code

program.

In addition to those actions, you can enter the part program for

complicated machining motions, which are usually difficult to make

by ISO-code form, as a

“Cycle machining” by using menu

programming method. This cycle machining is made in form of a

block including G-4digits and necessary data items.

In the following explanations, the contents of a square frame mean the

actual operations, and each operation are described as follows.

2.1.1

Setting of Z-axis Offset Data

(1) Set a standard workpiece on a chuck of lathe. After then, for

safety, take measure to keep fully safety such as closing the

machine door.

(2) Execute the machine reference position return of X-and Z-axis.

(3) Output T-code in MDI mode, and select the tool for measuring.

(4) Make a spindle rotate by fully safety speed.

(5) Cut surface A of the following drawing in manual mode with a

SETTING OF WORKPIECE COORDINATE SYSTEM SHIFT

DATA

After setting the geometry offset data for necessary tools, set the

workpiece origin on the actual workpiece used for machining.

On the lathe, the rotating center line of a workpiece is usually set to

workpiece origin of X-axis. So, the workpiece origin of X-axis need

not be set again for new workpiece.

For Z-axis workpiece origin,, you must set again for new workpiece

when you change to new one.

In this section, operations for setting the workpiece end surface to the

workpiece origin are described.

(1) Set the actually machined workpiece on a chuck of lathe. After

then, for safety, take measure to keep fully safety such as closing

the machine door.

(2) Execute the machine reference position return of X-and Z-axis.

(3) Output T-code in MDI mode, and select the tool for measuring.

(4) Make a spindle rotate by fully safety speed.

(5) Cut surface A of the following drawing in manual mode with a

actual tool.
