AUTO REPOSITIONING

When the worksheet edge which is clamped has a bend, curves or excessive burrs, enter

“G25” instead of “G27” to ensure accurate repositioning. These factors can cause inaccurate worksheet positioning when automatic repositioning is performed, unless the G25 code is used. When

is read, the same movement will be obtained as in the following:

2.4 mm

1.2 mm

G25 X

First the table moves 2.4 mm in the positive direction from the current position. Then the

carriage moves

from the current position and the table moves 1.2 mm in the negative direction. Next, the X and Y coordinate system is offset by Y1.2 to compensate for the difference between the table positions before and after the automatic repositioning. After “G25” is read, the punching range along the Y-axis is moved 1.2 mm in the negative direction from the standard punching range.

-11.4 to 1009.0 mm (-0.448” to 39.724”)

the retraction. The offset values designated by

PROGRAMMING PROCEDURE

1. Determining the processing method

2. Determining the clamp position

Position the clamps as far apart as possible and check the “dead zone” (see the DEAD

ZONE DIAGRAMS).

Checking the tool and station number

Ex.:

(a) Check to ensure the proper tool is used for the cut-out required.

150 mm dia. round hole

300

x 400 mm square opening

-nibbling with a 20 mm

-shear-proof punching with a 50 mm x

punch

50 mm square punch

(b) Check to ensure desired tools can be loaded into the turret.

Problem: Is the combined use of the following tools for one program possible?

50 mm dia., 35 mm dia., 80 mm.dia., 20 mm x 20 mm sq., and 30 mm dia.

(2” dia., 1.4” dia., 3” dia., 0.8” x 0.8” sq., and 1.25” dia.)

4. Determining the punching sequence

This must be determined by taking into consideration both the processing time and accuracy. General precaution

(a) Begin and finish with the upper right corner of the diagram. (b) Begin with small holes, then square openings, and notching. (c) The tools should not be selected -more than’ twice. (d) In multiple part punching, shearing of the worksheet should be done last.

5. Calculating the coordinates

Calculate the coordinate values in units of 0.01 mm (millimeters) or 0.001” (inches).

6. Checking.

Check the clamp positions, punching sequence and coordinate values.

The force required to punch the worksheet must not exceed the machine capacity. The required punching force is obtained by the following formula:

P (ton) =

A (mm) x t (mm) x

1000

where, P: Force required

A: Length of cut edge

t: Thickness of worksheet

I: Shearing strength of worksheet

Problem: Is it possible to punch holes with a diameter of 40 mm in a mild steel plate with a

thickness of 3.2 mm and a shearing strength of 46 kg/mm’ ?

Problem: Is it possible to punch a 20 mm x 20 mm square hole in a stainless steel plate with

a thickness of 3 mm and a shearing strength of 60 kg/mm5?

PART PUNCHING

GENERAL DESCRIPTION AND PROGRAMMING EXAMPLE

1. Multiple part punching function

This function is used to punch multiple products which have the same punching pattern from one worksheet. Once the punching of only one product is programmed, the punching

of multiple products with any desired layout on the worksheet can be performed by using

simple commands.

Removal of each product after .multiple part punching

When punching four products from one worksheet, such as the one depicted in the below, the following two removal methods can be used:

a. Micro-joint method

The hatched portions are punched out in the “Micro-joint method”.

Page 64

As shown in the figure, the hatched portions are punched out by rectangular punches in

such a manner that the four corners of each product remain unpunched. The four corners

are connected to the worksheet by means of an approx. 0.15 mm joint. After the entire punching process, the worksheet with punched products is removed from the

machine, and each product is then separated from the worksheet.

STORING OF PART PROGRAM

Part program

voo

To store the part program for one product,

“U” and a two-digit numeral (macro number)

must be entered at the beginning of the part program to be stored, and

numeral that was used by “U” must also be entered at the end of the part pro-

gram. The part program thus positioned between

“UOO” and

memory.

The same macro numbers must be attached to “U” and

one part program. Three types of macro numbers are available; one type ranges from 01 to 59, another type from 60 to 89 and the other type from 90 to 99.

The macro numbers 01 through 05 can be specified as one digit by omitting the

zero. On the macro numbers 01 through 89, the maximum limit of the part program allowed to be stored is 8000 characters on one processing tape.

Program example

In this example, the processing by one type of

tool is stored as a part program.

In this program, the processing by one type of tool is performed on the whole surface of the worksheet. Then,

next type of tool is

selected and the processing by it also is made

on the whole surface of the worksheet. The

time required for selection of tool can thus be

reduced.

Program example

In this example, the processing for one product by five types of tools is stored as a part program. All processing of one product is performed by using five types of tools. Then, all processing of the next product is also performed by using the same five types of tools. The time for selection of tools increases. Although the program is simple, the processing time is greater than in example above.

TRIAL PUNCHING, POST-TRIAL PUNCHING, AND FULL PUNCHING

In the conventional method of multiple part punching, punching must be accomplished over the whole surface of the worksheet, and then dimensional and accuracy checks must be conducted. Should the program contain any error, substantial worksheet and time losses would result. However, in this multiple part punching function, selection between three types of processing is available by key operation on the control panel, i.e. “trial punching for one

product”,

“multiple punching for remaining products after trial punching” and “full punch-

ing”.

DEAD

CLAMP DEAD ZONE A clamp dead zone is defined as any position in which the work clamp is so close to the

punching point that the clamp itself is punched, or in which the clamp rests on top of ad-

jacent dies or free-motion bearings, resulting in the worksheet being distorted if punching

is performed. When preparing the program, the position of the work clamps on the worksheet must be determined so that the clamps do not enter this dead zone during punching operation.

Clamp caught between punch and die. Clamp will be punched.

Clamp resting on top of adjacent die. Clamp will not be punched, but worksheet will be distorted.

Hole A position is in the area where the clamp will be punched and hole B position is in the area where the clamp rests on adjacent dies. Consequently, in order to punch these holes, the following methods must be considered:

Change the clamp position.

Provide extra clamping area.

Change the station to be used.

Change the tool size to be used.

e. Use the auto-repositioning function.
