NEW - HITCH FEED Push Bending
CNC Bender can now hitch feed during push bend to create a helical tube shape with many loops from a material that is much longer than the bender.
NEW - Push Bend Twist GEARING
CNC Bender now gears the rotational twist motion to the feed motion in order to create more accurate helical shapes. As the Feed axis moves forward, the Rotation axis rotates at a pre-programmed gear ratio in the Push Bending Profile page.
The Twist Velocity column is replaced with the Twist Gearing column. The gear ratio is a value can start at 0.002 units and increase.
The ratio is used as "degrees of twist" in the following formula:
Rotation Degrees of Twist / Feed Axis 1 Millimeter
So a twist gear of 1 would cause the rotate to twist 1 degree per the feed axis 1 millimeter of motion.
NEW - Automatic Bend Combine During XYZ to FRB Conversion
CNC Bender now allows you to automatically combine adjacent bends into a single bend if the adjacent bends meet a preprogrammed criteria controlled by the Low Level dynamic options.
This feature is important because centerline XYZ data always represents bends that approach and exceed 180 degrees as two separate adjacent bends.
|
This part was drawn in SolidWorks and extracted by Benderlink for SolidWorks into XYZ data. |
|
|
The data was imported into the XYZ data page of CNC Bender. |
|
|
When XYZ to FRB conversion is made without the Combine Bends feature enabled, the result is five bends as shown in this FRB page.
|
|
|
Enter the Low Level menu. The Combine Bends feature is enabled in the dynamic options.
|
|
|
When XYZ to FRB conversion is made again, there are now only 3 bends in the FRB data. The first two bends are combined into high-angle bends that are proper for CNC benders. |
|
|
This is the resulting image in CNC Bender Bender Data menu: |
