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
