When the '' optionDefine by profileIf the ''Profile'' box is checked, tabs will be added to the input field. These tabs will allow you to specify for each type of profile :


  • The choice of bar lengths : 

- Imposed length : 


 


Here we find the choice as defined in the zone ''.Machine & bars''. Possibility to reuse scraps.

With the '' optionImposedIf the ''Check'' box is checked, all other options are grayed out.


- Length ''Deducted between ...'' :


 


This option allows you to give a range in which the tool will calculate the optimum length to obtain a minimum of waste. This option also allows you to request a calculation of two optimum lengths.


  • Graphical analysis : 


The button is used to calculate the optimal bar length to obtain a minimum of fall.


The graph appears only in the case where the utility is asked to calculate the optimal bar length and this length is not imposed in the field ''.Choice of bar lengths''.


The option '' Iteration fineness '' allows to modify the fineness of iteration following this calculation:

(Lg max - Lg min)/finesse, i.e. for the above example (7000-4000)/100 = 30 iterations.


 


In these 2 graphs, are visualized :


- In orange the main lengths optimized and recommended by the tool.

- In blue the % of fall for a given bar length.

- In green the number of bars required.


Example:


 


If I run the analysis with the above parameters :


 


It appears from the analysis that the optimal bar for obtaining a minimum drop is a bar of 5700 (1.21% drop).

If you want to use another bar length, you have to force the length in ''Raw bar lengths''.

For example: Use a 5500 bar.

 

The report will take into account the selected bar.


  • Separate the flows into batches :

If a number of bar lengths greater than 1 is requested, the tool will separate the longest lengths from the shortest. Here the user will be able to intervene on the separation length of the batches.


- Example with a list of flows with different lengths.


 


The button allows you to display the different lengths of bars.


 


The slider is used to select the batch separation length.

A batch in bluewith cut lengths of 2200; 2210

A batch in orange with cut lengths of 1210...; 550


- After defining the batches, the graphical analysis must be launched to calculate the optimal bar lengths.


 


It appears, during the analysis, that the optimal bar for the batch in blue is a bar of 4600 (1.74% drop) and for the batch in orange of 5400 (1.7% drop). By default, the report will take into account these bars.

If you want to use another bar length, you have to force the length in ''Raw bar lengths''.

It is possible to impose only length 1 or length 2.

The report will take into account the selected bars.
