INPUT

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

“G25”

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

2.4 mm

1.2 mm

t

G25 X

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

carriage moves

X-

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.

(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) =

(kg/mm’)

where, P: Force required

A: Length of cut edge

t: Thickness of worksheet

I: Shearing strength of worksheet

When a pattern instructed by the codes G26, G28, G29, G36, G37, G66, G67, G68, G69,

G78 or G79 is used repeatedly, the pattern can be memorized and recalled whenever re-

quired. To memorize a pattern, enter the address letter “A” along with a one-digit numeral

(from 1 to 5). To recall the pattern, enter the address letter “B” and the same one-digit numeral as that was used by “A”.

MULTIPLE

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.

2.

Removal of each product after .multiple part punching

When punching four products from one worksheet, such as the one depicted in the

figure

below, the following two removal methods can be used:

a. Micro-joint method

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.

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,

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 (1 I above.

minimized.

(b) If the processing of a part program starts from the upper right corner (Q4) and ends

at the upper left corner (Q3), the processing of the next part program should start at the upper left corner (Q3) in order to guarantee efficient movement.

(c) When cutting the outside shape in the process of punching multiple products, it is

desirable to start the punching at the upper portion of the worksheet and move lower in sequence. For such a procedure, enter the command of: G75 WOO Q4 or 3.

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”.

Refer to Page 13 of the OPERATOR’S MANUAL.

CLAMP

DEAD

Z-ONE DIAGRAM

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.

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:

a.

Change the clamp position.

b.

Provide extra clamping area.

c.

Change the station to be used.

d.

Change the tool size to be used.

e. Use the auto-repositioning function.
