Bend-Tech provides the proper cut lengths, bend locations, bend angles, and rotations for all machines.
With this information Bend-Tech calculates the spring back angles for each job. Bend-Tech creates its own internal formulas from a data history file of the materials, tooling, and machines. From this, the values will be obtained in the Bend-Tech tooling library to calculate the correct bend lengths. Can elongation be calculated?Ībsolutely! We have a simple testing procedure that is performed with the tooling and material. In an instant the manufacturing details are available. Within Bend-Tech, select the tooling corresponding to the radii in the part or allow Bend-Tech to select it for you from a tooling to radius relationship table. If the tube is longer and cannot be cut, this incorrect calculation of the laser cutting position has resulted in irreparable damage to the entire tube processing procedure.After completing the tube design in SOLIDWORKS, select the Bend-Tech icon within the SOLIDWORKS framework and select the green check to send the part into Bend-Tech. Calculating the laser cutting position incorrectly means that the resulting bent tube will be longer or shorter than it should have been. The value for the length of the tube bend is also important for determining the exact point at which the laser cut needs to be made, as well as the length of this cut. This value will vary depending on tube diameter and wall thickness, as well as the average bend radius and alloy percentages.Ī Ø30 x 2 mm steel tube with the same radius as a Ø30 x 2 mm aluminium tube will nonetheless have a different coefficient. To calculate the exact length of the bend, the product of the above formula must therefore be divided by another coefficient – known as the coefficient of elongation. This elongation can have the following consequences:
