Bending Formulas / Definitions
Monday, 22 June 2009
Bend Allowance = Angle * (PI / 180) * (Radius + K-factor * Thickness)
Bend Compensation = Bend Allowance – (2 * Set Back)
Inside Set Back = tan (Angle / 2) * Radius
Outside Set Back = tan (Angle / 2) * (Radius + Thickness)
Bend Allowance – The length of the arc through the bend area at the neutral axis.
Bend Angle – The included angle of the arc formed by the bending operation.
Bend Compensation – The amount by which the material is stretched or compressed by the bending operation. All stretch or compression is assumed to occur in the bend area.
Bend Lines – The straight lines on the inside and outside surfaces of the material where the flange boundary meets the bend area.
Inside Bend Radius – The radius of the arc on the inside surface of the bend area.
K-factor – Defines the location of the neutral axis. It is measured as the distance from the inside of the material to the neutral axis divided by the material thickness.
Mold Lines – For bends of less than 180 degrees, the mold lines are the straight lines where the surfaces of the flange bounding the bend area intersect. This occurs on both the inside and outside surfaces of the bend.
Neutral Axis – Looking at the cross section of the bend, the neutral axis is the theoretical location at which the material is neither compressed nor stretched.
Set Back - For bends of less than 180 degrees, the set back is the distance from the bend lines to the mold line.

Tharsus Engineering to exhibit at Defence Industry Exhibition
Friday, 12 June 2009
Tharsus Engineering will be exhibiting at the Defence Equipment and Systems International (DSEi) 2009 event to be held in London in September.
DSEi is the largest fully integrated defence exhibition in the world and features the full capability of the international defence and security industry at a single exhibition.
Tharsus, first time exhibitors at this event will be promoting their specialist CQI fabrication division at Blyth which supplies customers with products which are produced in a Controlled environment using production processes and systems of known capability by fully Qualified personnel. The scheduling and line-side delivery of product is then configured to Integrate with customers’ processes and systems.
Tharsus will be exhibiting alongside other Northern Defence Industries (NDI) member companies at the four day event to be held at the ExCeL Centre in London’s Docklands.
Anyone interested in visiting the event to view over 1,350 exhibitors, please contact fran.jonas@tharsus.co.uk, to be added to Tharsus’ Exhibitor Guest list, which entitles you to free pre-registration and fast track event entry.
