COPRA® Professional Design Module for Sections (M1) and
COPRA®Professional Design Module for Trapezoidal Sections (M2)

The COPRA Professional Design Module for Sections is the software package for every roll form designer. It allows you to do a really professional roll form design for simple as well as most complex shapes. It includes functions like... 

project manager and data archive
section design library
'punched holes' function
static properties calculation
strip width calculation
design of the flower pattern
COPRA bending sequences for automatic flower design
Design of flowers for combination tool sets
interactive tube unfolding functions
calculation of strip edge strain (wire frame model)

COPRA combines the most flexible methods to design profile shapes on the computer screen:
COPRA has got a library of standard shapes;
Section design via macro technology:
COPRA offers a variety of forming elements;
COPRA also offers direct entry (list editor);
No "external" CAD-construction of profile sections required.
COPRA is integrated in CAD systems, i.e. designing is simply done within the CAD program (keeps the learning curve down to a minimum).
COPRA allows designers to "mix up" or switch between the possibilities available!

static properties calculation
COPRA calculates the static section codes and prints out result lists or adds the results to the CAD display on screen together with the reference system.
The reference system can be selected independently (strain directions!) The user is free to choose whether it is an open or a closed profile (e.g. an unidirectional lock seams). Even punched profile sections will be considered!
The calculation programs in the COPRA program system will determine:
area
weight
coordinates of center of gravity
geometrical moments of inertia
section modulus
torsional geometrical moments
vaulting resistance
coordinates of load center

'punched holes' function

The user is not only able to unfold the profile. He can even bend up (fold) individual elements. For practical applications this means that users are not restricted to work from the finished flower to the flat sheet. During the process he can bend or over bend individual areas (even straight elements!). Experience has shown that functions like these are especially important, in order to, for example, open undercuts (to be able to form them with top or bottom rolls).

There are much more than just three arc types. With COPRA, users have even more powerful methods at their disposal:
With each unfolding step the user can freely choose the desired calibration method. 
It would be quite inflexible, if an arc type could only be selected once. 
Instead, the user selects calibration method and profile element via mouse click on screen and chooses the respective unfolding or bending angle and immediately the new geometry will be displayed on screen. 
It is no problem to change between constant radius method and power bending (or any other procedure)

The following calibration methods are available:
Arc bending, 
constant radius method - the method allows to calculate the length compensation pieces in  front and at the end or with any mixed up distribution (percentage).
Of special importance is thereby the so-called track-holding unfolding method, during which the compensation pieces are calculated in a way that the strip guide is straight (important with undercut shapes, where material flow is impaired, e.g. dovetailed shapes).
Track-holding unfolding is again a unique COPRA feature!
If the constant radius method under COPRA is used, a compensation element can furthermore be positioned at the center of any arc (can be selected by the user in the respective dialogue box).
For lock-seams or sharp edges (internal radius = 0) COPRA also provides a calibration method (the so-called Angle/Radius Method).
Arc profiling should not be confused with... 
...tube profiling, which is also implemented in COPRA. The method allows to unfold arc elements even if adjacent features are not straight. The method was especially developed for round tube forming or for open profiles with similar pre-requisites.

With only three arc types as provided in literature and competitive  design software programs, the needs for complex or difficult roll form applications can never be covered!

some software demos...

Single parts of flower patterns or forming passes can be combined to new variations/ variants of designs. Gauge (sheet metal thickness) can be modified - for all passes in one command, even if you have already finished the whole flower design using various (even different) calibration methods.

COPRA bending sequences for automatic flower design
This is a database-supported software module for automatic unfolding of profile sections.

This allows users to exchange and combine section or flower parts in order to perform an effective design for combination tool sets.
The increasing variety of forms of roll-shaped profiles with at the same time decreasing lot sizes will force the manufacturer to take far-reaching measures to streamline production. As the production of roll tools is on the one hand expensive and on the other hand cannot often be integrated into unit prices the application of combination tool sets is the obvious solution.
Manufacturing costs will be allocated to several orders and, thus, the utilization ratio will increase considerably. This might begin with the utilization of a tool set for the production of similar profile forms with different dimensions and in extreme cases lead to exclusive use of standardized shapes.
Each of those applications has its special requirements which COPRA - in relation to the problem -takes into account. COPRA provides the following functions:

Automatic adaptation of an existing profile flower to various dimensions. Profiles similar in form, thus, only have to be unfolded once
Combination of different, already unfolded profile half
Automatic combination of the roll tools
Documentation of the required spacer widths
Optimization of the required spacers relative to total length and weight
Management of the roll stock by a professional database-management-system

Your advantage:
From now on, for a profile section e.g. in three dimensions you will only have to unfold one profile.
By simultaneous visualization (overlapping with different colors) of profile flower and basic dimensions of the roll tools you may detect at once where a roll has to be modified or spacers have to be inserted.

COPRA®, however, offers an even more accurate and effective simulation software for the calculation of theoretical strain values and the optimization of roll tool sets: COPRA® DTM (COPRA Deformation technology Module - a simulation method of the "3. generation") and  COPRA® FEA RF, a non linear finite element simulation tool.

The COPRA Professional Design Module for Trapezoidal Sections is the software package for the roll form designer working with corrugated or trapezoidal sections.

It includes similar functionality as the Section Design Module, plus
calculation of an optimized forming sequence (for trapezoidal shapes)
calculation of horizontal material movements
and contains also semi automatic roll tool design 
(only in combination with H1 - module for roll design)

System requirements
What are the requirements for a successful operation of COPRA ?
COPRA is available for  Windows operating systems and requires AutoCAD or Mechanical Desktop (both registered trademarks of Autodesk). AutoCAD is not included in the COPRA software unless you order a COPRA stand alone option.
