IRIS Plus (Pre-release)

The Lazer Safe® IRIS Plus is a real-time optical angle measurement and correction system integrated into the press brake’s safety photocells. It uses a laser transmitter and a high-speed camera receiver to measure and correct bend angles during the bending process.

Core capabilities

Real-Time Measurement: The camera captures live frames of the bending profile, measuring the angle and calculating spring-back in real time.
Active Angle Correction: The system sends measurement data directly to the CNC controller, enabling instantaneous depth adjustments to match the programmed angle.
Non-Contact Technology: The system uses optical image analysis instead of physical contact with the sheet metal. This prevents surface marks, eliminates collision risks, and does not restrict operator movement.
High Precision: Measures angles with accuracy better than 0.1° (depending on setup), reducing scrapped parts and the need for test bends.

Default mode for programs

On the same page, the AMS setting controls how Default mode for 3D program are assigned to bends in 2D and 3D programs:

Mode	Description
None	All bends are set to "None" with no reference. Assign Identify or Learned mode to each bend manually.
Auto	AMS modes and references are assigned automatically for all bends.

Mode

Description

None

All bends are set to "None" with no reference. Assign Identify or Learned mode to each bend manually.

Auto

AMS modes and references are assigned automatically for all bends.

When set to Auto, some bends may still display as "None". Verify and adjust modes as needed.

Calibration

Calibration ensures accurate angle measurement. Perform calibration when the IRIS Plus sensor is selected.

Reference image

A reference image captures the exact position of the punch tool tip. It is recommended to capture a new reference image at least once a week.

Calibration procedure

Run a program and navigate to the setup sheet. The Calibrate button is available for IRIS Plus AMS.
On the IRIS AMS calibration page, click Tool Align. The AMS captures a reference image and displays a confirmation message.
Mount the suggested calibration tool on the machine and click Done. The calibration page displays three options: Left, Middle, and Right.
Select the side where the calibration tool is placed and click Calibrate. Repeat for all three sides.
The calibrated values (Acute, Main, and Obtuse) are updated on the page.
After completing all three sides, click Done.

The calibration tool type depends on the punch shape:

Triple-angle side — Use with Straight or Pointed punches.

① Pointed punch

Double-angle side — Use with Gooseneck punches.

② Gooseneck punch

AMS modes

AMS operates in three modes:

None

AMS is inactive. No angle measurement or correction is performed.

Identify

In Identify mode, AMS measures the spring-back and calculates corrections automatically:

AMS bends to the initial angle (target angle + SB measure angle).
During decompression, it calculates the spring-back and determines the correction.
It applies the correction to achieve the target angle.
The correction values are stored for use by subsequent bends in Learned mode.

Bending sequence: Fast Closing → Slow Closing → SpringBack Measure → Decompression → Pressing → Decompression → Opening

Before BDC settings

Before BDC settings
Setting (Range: 1 to 2)	Description
Before BDC = 1	AMS bends to the initial angle (Target angle + SB measure angle), then decompresses to calculate spring-back and corrections. On the next pressing, AMS moves to the LDP point targeting: Target angle - SpringBack value. If the target angle is not reached at the LDP point, corrections are applied at the same point. Once the target angle is achieved, the RAM decompresses and AMS recalculates spring-back. Bending sequence: Fast Closing → Slow Closing → SpringBack Measure → Decompression → Depends on "After BDC" setting
Before BDC = 2	AMS bends to the initial angle (Target angle + SB measure angle), then decompresses to calculate spring-back and corrections. On the next pressing, AMS reaches the target angle, stops, and decompresses to recalculate spring-back. For subsequent pressings, AMS moves to the LDP point targeting: Target angle - recalculated SpringBack value. If the target angle is not reached at the LDP point, corrections are applied at the same point. Once the target angle is achieved, the RAM returns to decompression. Bending sequence: Fast Closing → Slow Closing → SpringBack Measure → Decompression → SpringBack Measure 2 → Decompression → Depends on "After BDC" setting

After BDC settings

After BDC settings
Setting (Range: 0 to 1)	Description
After BDC = 0	AMS measures the final angle after decompression, then proceeds to the opening state. No corrections are applied. Sequence: Pressing → Decompression → Opening
After BDC = 1	AMS measures the final angle after decompression. If corrections are still required, AMS re-presses to the same LDP point. Sequence: Pressing → Decompression → Pressing → Decompression → Opening

Learned

AMS mode selection page with After BDC settings

In Learned mode, AMS uses the correction values obtained from a previous Identify bend as a reference:

After BDC settings
Setting (Range: 0 to 1)	Description
After BDC = 0	Correction values from the Identify bend are applied. AMS measures the final angle after decompression, then proceeds to the opening state. Sequence: Fast Closing → Slow Closing → Pressing → Decompression → Opening
After BDC = 1	Correction values from the Identify bend are applied. AMS measures the final angle after decompression. If corrections are still required, AMS re-presses to the same LDP point. This compensates for differences in sheet thickness. Sequence: Fast Closing → Slow Closing → Pressing → Decompression → Pressing → Decompression → Opening

Setting the reference bend

Select a bend from which Identify mode corrections were obtained. Only bends with the same target angle should be used as a reference.

Set up AMS for a bending program

The AMS workflow is the same for 2D, 3D, and Direct programs. The following example uses a two-bend Direct program:

Set the AMS mode for both bends.
On the Run page, click Correction → Angle Measurement to open the mode selection page.
Set the first bend to Identify and the second bend to Learned, with the reference set to Bend 1.

In 2D and 3D programs with Default mode for 3D program set to Auto, modes are assigned automatically.
Start the bending process. After the first bend completes in Identify mode, the angle correction and spring-back values are displayed in the Angle field on the Run page.
The correction values from the first bend are applied to the second bend automatically. The final angle is displayed after the second bend completes.

To view detailed angle measurement data:

Navigate to Settings → Other Settings → Machine Settings → General Parameters → Log → Diagnostics.
Enable Show IO Screen and save.
On the Run page, click Numeric and expand Angle Measurement Data.

Troubleshooting

The following table lists common AMS error messages and their causes:

Error message	Cause and resolution
