Die Library

Description

The die library stores all the dies available to bend parts. Each die is assigned a set of attributes such as name, stamped CLR, calibrated CLR, minimum distance before a bend, minimum start length, minimum end length, and minimum distance between bends with and without rotation.

Each die can be calibrated using the calibration function and there is a list of predefined dies from a number of different bender models.

In the die library window, there is a list of all dies in the library on the left. The add and delete buttons are located below this list. To the right, the attributes of the currently selected die are shown. The calibration, die list, and save buttons are situated below the attribute fields.

How To

Start Up

To access the die library, click on the settings menu on the main tool bar. Click the die library option in the drop down menu.

Attributes

Each die is defined by a set of attributes. See image below.

• Die Name: The name given to the die. This will be the what the die is called throughout the software.

• Stamped CLR: The CLR value that the die was given. Typically this is stamped directly onto the die.

• Calibrated CLR: This is a value that is generated and used by the software to ensure accuracy. In general, this value should be 5 to 20% larger than the achieved CLR (the actual CLR that the die will produce). To get this value, the calibration wizard or the OEM Die List must be used.

• Bend Location Offset: The offset distance between the mark on the tube and the actual starting point of the bend. For example, if the bend offset is 0, the bend starts exactly where the mark is placed.

• Default: When the default check box is checked, the currently selected die will be the default die. The default die will be automatically selected in the die selection menu when a new part design is opened.

• Minimum Start Length: This is the shortest amount of tube length allowed at the very beginning of the tube before the first bend. This measurement will start at the starting end of the tube and end at the start of the first bend when the bend is as close to the starting edge as possible.

• Minimum End Length: This is the shortest amount of tube length allowed at the end of the tube after the last bend. The measurement will begin at the ending edge of the last bend and end at the end of the tube when the bend is as close to the end of the tube as possible.

• Minimum Distance Between Bends without Rotation: This is the shortest amount of tube length allowed between bends that have no rotation.

• Minimum Distance Between Bends with Rotation: This is the shortest amount of tube length allowed between bends that have rotation. For example, the distance allowed between two bends with a 180° between them.

Note: The minimum start length, minimum end length, minimum distance between bends without rotation, and minimum distance between bends with rotation will be used to check for manufacturing errors if the manufacture checking plug-in is included with the current version of software.

Add Die

Manual Entry

To manually add a die to the die library, click the add button below the die list. After add is clicked all the attribute fields to the left will be cleared out. Enter the information into these fields and click the save button to add the die to the library.

OEM Die List

First click the OEM Die List button. This will open up a new window (seen to the right) where dies can be searched for and added to the library.

A list of all the dies currently in the library will be shown on the left side of the window. In the middle there will be a machine/bend drop down menu and a selection menu where the material shape and measurement can be chosen. Below the menus, the die information will be shown once a die is selected from the right die list. To the far right, a list of available dies for the machine and material will be shown once a machine is selected.

To add a die from the OEM die list, first a machine must be selected. Click on the drop down menu and choose a machine from the list.

Once a machine is chosen, the list of dies for that machine will be generated in the list to the right. The list will only show the dies that will use the selected material shape and measurement. To change the material shape/measurement of the dies in the machine's die list, click one of the material options below the machine menu, as shown below.

When a die is selected, it's attributes will be generated. The stamped CLR, achieved CLR, calibrated CLR, minimum distance before bend, and serial number will be displayed.

• Stamped CLR: The CLR value that the die was given. Typically this is stamped directly onto the die.

• Achieved CLR: The CLR that the die will actually produce when bending. This value compensates for spring-back and other factors that contribute to inaccuracies in the CLR of a bend.

• Calibrated CLR: The calibrated CLR of the die. See the calibrated CLR definition in the Attributes section.

• Bend Location Offset: The die's bend location offset. See the bend location offset definition in the Attributes section.

• Serial Number: The die's serial number.

Once the proper die has been found and selected, click the add button to add it to the die library. A message box will appear where a new name can be applied to the die. Give the die a new name or keep the default name then click the green check button to add it to the library. Once added, it will also appear in the die library list on the left of the window.

Dies can also be deleted from the die library within the OEM Die List window. To delete a die, select the die in the die library list by clicking on it. Click the delete button to remove it.

Edit Die

To edit a die's attributes, first select the die by clicking on it in the die list. Change the values as necessary and click the save button to confirm the changes made.

Remove Die

To remove a die from the die library, first select the die by clicking on it, then click the delete button.

Die Calibration Wizard

The die calibration wizard is used to produce the calibrated CLR for a die. This value is specifically used only within the software to ensure accurate results when designing parts. To calculate this value, a small piece of tube must be bent to 90° with the die. Measurements, such as the bender type, die CLR, the material diameter, the distance from the end of the tube to the mark, and each leg length must be supplied. Once completed, the calibrated CLR and bend location offset values will be calculated.

To access the die calibration wizard and calculate the calibrated CLR for a specific die, select a die in the die list and click the calibration wizard button. Another window will open that will step through the process of finding the calibrated CLR. Use the blue arrow buttons at the bottom of the window to navigate.

At the end, the achieved CLR, calibrated CLR, and the bend location offset will be displayed, seen in the image to the right. Click the green check button to confirm and generate these values in the appropriate fields of the current die. In the die library window, click the save button to save the new values.

Warning: Calibrated CLR should be 5 to 20% larger than the achieved CLR. If the calibrated CLR result does not reflect this, please go back through the calibration wizard and double check the values.

Help Videos

Below the attribute fields there will be a blue question mark button. See image to the right. When this button is clicked, some of the attributes will have small help icons displayed next to them. To hide the help icons, click the question mark button again.

Click on any of these help icons to access help videos that will visually explain what a certain attribute is or how to use a certain button or function. See image below. Use the play, pause and stop buttons in the bottom left corner of the window to control the video. Click the grey X button to close the video.
