2.2 Operation Flow

2.4 Multi-Step

• Description

You can program the bending steps for the different settings on this page. Multi-step programming is commonly employed for the complex bending, which consist of many different bending steps.

Press F2 key to enter the Multi-Step page, as shown in Figure 2-4.

• Example

We take the following process as an example to describe the programming.

2.5 Manual Movement

• Press the arrow keys UP and DOWN to select the desired servo-axis.
• Press the arrow keys LEFT and RIGHT to select proper movement direction.

2.6 Die Settings

To program the process by the given angle, it is necessary to set parameters of the die.

Press F4 key to enter the Die page, as shown in Figure 2-6.

• Press arrow keys UP and DOWN to select the desired die ID.
• Press arrow keys LEFTand RIGHT to select the desired parameter of the die.
• Press NUMERICkeys to type the proper value.

The technical parameters diagram of the die are as shown in Figure 2-7.

• H: The height of the die, which is used in the bend depth calculation.
• V: The length of V-opening, which is the distance between the touching lines crossing.
• α : The angle of the die.
• R: The radius of the edges of the V-opening.
• S: Safety distance, which will be used in the case an R-axis,is mounted. This to prevent finger to die collision. The indicated minimum value iscomputed automatically from the die dimensions as follows:
  S = FS＋V／2, in which:
  FS = flat section on the back side of the V-grove
  V = opening value.

2.7 Bend Correction

It is necessary to commission the machine before your actual processing, in order to win an accurate bending result.

For performing it, you can program a bending process on Single-Step page, and operate the machine to complete one processing.

Then, measure the actual bending angle, bending depth, and the distance of the back gauge.

Check whether the bending result is corresponding with your requirement.

• Angle correction

The range of this parameter is from -90 to 90.

When the actual axis position is not corresponding with the displayed value, it is possible to correct the position with this parameter.

For example:

• When the programmed and displayed value is 90, while the actual axis positionvalue is 92, then you shall set the Corr. α to -2.
• When the programmed and displayed value is 90, while the actual axis positionvalue is 88, then you shall set the Corr. α to 2

• Y-axis correction

The range of this parameter is from ﹣99.999 to 99.999.

When the actual axis position is not corresponding with the displayed value, it is possible to correct the position with this parameter.

It may be repeating to set Corr. Y. However, we can learn from experience, program the process by the given angle, and measure the depth of 1 degree as the unit length. Then, program the process by the given depth, and set Corr. Y according to the unit length. Repeat this operation, until the bending result is corresponding with your requirement.

• X-axis correction

The range of this parameter is from ﹣99.999 to 99.999.

When the actual axis position is not corresponding with the displayed value, it is possible to correct the position with this parameter.

The setting of X-axis correction is same with Angle correction. For example:

• When the programmed and displayed value is 100.00, while the actual axis position value is 102.05, then you shall set the Corr. X to -2.05.
• When the programmed and displayed value is 100.00, while the actual axis position value is 98.05, then you shall set the Corr. X to 1.95.

2.8 Program Management

2.8.1 Create a Program

Press F5 key to enter the Program page, as shown in Figure 2-8.

Move the cursor on the program Name, and press NUMBERS keys to type a desired name. The typing method is 10 keys, that is, the numbers and letters on the same key can be switched by pressing severaltimes. For example, 2, C and D are in the same key, press once, shown as 2; quickly press twice, shown as C; quickly press three times, shown as D. Press ENTER key to confirm your typing, the software can generate the Steps, Die and Date.

2.8.2 Edit the Program

Move the cursor on the program ID you want to edit, and press ENTER key to enter the Multi-Step page. In addition, when you enter the Multi-Step page, the selected program has been loaded.

For details about the program see the section 2.4 Multi-Step.

2.8.3 Delete a Program

Move the cursor on the program ID you want to delete, and press CLEAR key. The page can display a dialog for asking whether to delete the selected item. Press OK to delete the selected program.

2.9 Teaching

In order to obtain the position values of the servo axes, the user needs to perform Teaching operation before the bending process, which can indicate the current position of the servo axis.

The diagram of machine coordinate system is as shown in Figure 2-9. You can refer to this diagram to complete the teaching value of the measurement and set.

Type the password 1212 in Constant page to enter TechIn Para page, as shown in Figure 2-10.

Press the arrow keys UP and DOWN to select a parameter, and type the desired value for them.

• Y Teaching and Clamping Point

The purpose of teaching Y-axis is obtaining the comparativeposition value of clamping point. When you teach Y-axis, it is necessary to estimate the position value of the Y-axis in advance. For example, if the position of the Y-axis is estimated to be 50mm, and the procedureis as follows:

Step 2 Select the parameter Y Teaching in TechIn Para page, and set it to 50.

Step 3 Return to the Single-Step page, and set the parameter Angle to 180, and the other parameters can be set arbitrarily.

In general, when the machine is in clamping, the punch just against the top of the sheet, so the bending Angle is set to 180, in order to ensure that the sheet was clamped.

Step 4 Run the device, and record the Y-axis position displayed on the device when the process is in Dwell.

Step 5 Enter the TechIn Parapage again, and fill the recorded value in the parameter Clamping Point.

• X Teaching

To teach the X-axis, you can measure the actual position of the X-axis, that is to say, measure the linear distance between the V-opening center of the die and back gauge.

Although there are many methods for teaching X-axis, their purpose is to ensure the processing accuracy. It is recommended that the user can run the machine once after roughly measuring the distance, that is, program a simple Single-Step program. For example, the measurement of the X-axis distance of 100mm, and the procedureis as follows:

Step 6 Select the parameter X Teaching in TechIn Parapage, and set it to 100.

Step 7 Return to the Single-Step page, and set the parameter X-axis to 100, and the other parameters can be set arbitrarily.
Here we need not to consider the error from the machine itself.

Step 8 Run the machine. When the bending step has been completed, measure and record the worked sheet.

Step 9 Enter the TechIn Para page again, and fill the recorded value in the parameter X Teaching.

• R Teaching

To teach the R-axis, you can measure and record the actual position of the R-axis directly, that is, measure the vertical distance between the top of the die and the back gauge. Then, enter the TechIn Para page again, and fill the recorded value in the parameter R Teaching.
