Cutting parameters

From Opera Wiki

The cutting parameters setting window

N.B: To access this box in Opera JobManagement: from the Workshop menu, select the Cutting button.

The cutting parameters are very important in Opera. The program retrieves information and data from them, which are then used in the technical development of the job. Therefore, operators are advised to take great care when creating these archives to avoid inconsistencies or errors.

Here is a description of the panel content

Job optimization parameters

• ID codes style : In this box, you can choose from fifteen types of identification code display, listed below:

NOTE:
The identification code helps, during assembly, to identify cuts and fillings belonging to a job. This code is automatically linked to the job but can be modified. The same code can also be printed on labels.

• Job.PartID: Displays the job ID code followed by the serial number of the piece. Example: CK.26
• Job.Typology.PartID: Displays the job ID code, then the type ID code and the progressive section number. Example: CK.FIN.26
• Job: Displays only the job ID code. Example: CK
• Job.Typology: Displays the job ID code followed by the type ID code. Example: CK.FIN
• SideNo.Sash: Adds a numeric specification from 1 to 4 for each side. It also adds a progressive number following the number of doors of the type.
• Job.Typology.SideNo.Sash: Similar to the previous entry, but also adds a type ID code. Example: 01.1
• CommTpgLeafSide: Similar to the previous entry but also includes a job identifier. Example: BM.01.3
• Typology: Displays the type ID code. Example: FIN
• Typology.PartID: Displays the type ID code followed by the section’s serial number. Example: FIN.26
• W/H: Adds the specific height/width code for the respective sides of the type.
• Typology.W/H: Creates a code identifying the type and the height/width position of the blank.
• Job.Typology.W/H: Same as above but with a job identifier.
• Side.Sash: Generates a code identifying left/right section position.
• Typology.Side.Sash: Similar to above, but also adds a type identifier.
• Job.Typology.Side.Sash: Identifies left/right blank position, type, and job.
• SashType: Generates a code indicating that the leaf is Left (S), Right (D), or CENTRAL.
• Typology.SashType: Similar to above, but with type coding.
• Job.Typology.SashType: Similar to above, but also includes job coding.
• Job.Typology.SideNo.SashID: By setting this item, the code generated by the program will show the job identification code, the typology identification code, the side number, and the sash ID.
• Job.Typology.Side.SashID: By setting this item, the code generated by the program will show the job identification code, the typology identification code, the side reference, and the sash ID.
• Job.IDBarcode: By setting this item, the code generated by the program will show the job identification code together with the ID barcode.
• Job.Typology.IDBarcode: By setting this item, the code generated by the program will show the job identification code, the typology identification code, and the ID barcode.
• CommTypMT: By setting this item, the code generated by the program will show the job code, the typology code, and the mullion/transom reference.
• TypMT: By setting this item, the code generated by the program will show the typology code and the mullion/transom reference.
• Mullion/Transom: By setting this item, the code generated by the program will show the mullion/transom reference.

• TypMT-Ext: By setting this item, the code generated by the program will show the typology code, the mullion/transom reference, and the external reference.
• Mullion/Transom-Ext: By setting this item, the code generated by the program will show the mullion/transom reference and the external reference.
• Custom: By setting this item, the code generated by the program will follow a customized format defined by the user or by the program configuration.

• Reinforcement : Defines how reinforcement codes (used in composite profiles, especially PVC) are displayed in the profile ID code printing, independently of the profiles themselves.

• Panes : Similar to the previous fields, defines the ID code settings for fillings.

• Typologies : Similar to the previous fields, defines the ID code settings for typologies.

• Profile prefix type in job : Defines the prefix type in the job identification code. Opera, when creating a new job, generates a code to identify it, which is then reused in technical printouts. Options:

• Literal: Two alphabetic characters.
• Serial number: Progressive job number.
• Name 1 / 2 / 3 / 4 charac.: Uses 1–4 initial letters of the job name given by the operator.
• YearLiteral: Four alphabetic characters.

• Structure ID separator: Defines the separator type used to add the structure ID to the typology prefix.

• Enable cut grouping by job: When enabled, generates ID codes for cuts that can be merged within the job.

Profile optimization parameters

• Units of measurement : Unit of measurement used for cuts and optimizations.
• Bar length U.M. : Unit of measurement for bar lengths in the archive.
• Cutting list length U.M. : Default unit of measurement for cutting lengths.

Optimization parameters for cutting lists

Optimization type selection menu

• Optimization type : This field opens a drop-down menu where it is possible to set the type of optimization that the program must perform for that job.

None

By setting this item, optimization will never be performed.

Standard

By setting this item, optimization will be performed by carrying out the necessary steps to obtain the best cutting system. Recommended setting.

Fast

By setting this item, optimization will be performed as quickly as possible to obtain the best cutting system. However, this setting may not provide satisfactory results.

Optimize bar

Allows the bars to be optimized without considering the standard profile length, but based on the lengths set individually for the profiles in the archive. Review the Optimization parameters section in Section 1, Profiles archive chapter, the button.

Length

If it is not essential to maximize bar usage and you prefer to prioritize cutting speed, this option allows the cuts to be performed by ordering the pieces by length, from longest to shortest. In any case, the remaining part of the bar will be completed with a cut compatible with the length still available.

Single length

In this case too, optimization is performed by length, ordering the pieces from longest to shortest. However, the remaining part of the bar is not “filled”: it remains empty, so as to ensure a continuous cutting sequence, without inserting intermediate pieces.

List

Optimization is generated by calculating the values of the list loaded in the Profiles archive, again through the Optimization parameters function .

Job position

Optimization is generated by taking into account the position within the job. In any case, the remaining part of the bar will be completed with a cut compatible with the length still available.

Job position strict

Optimization is generated by taking into account the position within the job. However, the remaining part of the bar is not “filled”: it remains empty, so as to ensure a continuous cutting sequence by position.

• Min. offcut: this is the minimum offcut length in optimization.
• Min. offcut for offcuts: this is the minimum offcut length in offcut optimization.
• Min. leftover: This is the minimum measurement that the program will use as a reference to consider the remainder of a bar as a reusable leftover. This field is enabled if Standard or Minimum leftover is chosen in the previous field.
• % leftover reuse: indicates the reuse percentage to be applied for waste calculation.
• Optimization steps: This is the value that indicates to the program the measurement for the change step in optimization. Usually this value is entered by the programmer. It is therefore recommended not to modify the value or to contact the technical support center.
• Optimization ratio: this is the acceptable offcut factor on a bar in grouped optimization.

Optimization parameters for panels

• 2Doptimization type : determines the strategy to be adopted for flat optimization.

• Guillotine: performs flat optimization following the sheet line and the dimensions of the panels and/or fillings, also showing how much of the sheet is not used.
• SkyLine: performs flat optimization by arranging the fillings and/or panels to be optimized based on their dimensions and orientation in the types, horizontal or vertical, but does not show how much of the sheet is not used.
• Rectangular: performs flat optimization following the shape of the fillings and/or panels to be optimized based on their dimensions, but does not show how much of the sheet is not used. It is a type of optimization used in laser cutters.

• Multi-process flat optimization: enabling this field allows the use of multiple processors for calculating flat optimization.

Optimization parameters for glass

• Metric glass rounding: specifies the rounding value for glass measurements in the metric system.
• Imperial glass rounding: specifies the rounding value for glass measurements in the imperial system.

Cutting list optimization parameters

• Optimization type : Determines the type of optimization.

• None: No optimization performed.
• Standard: Performs optimization with the best cutting method. Recommended.
• Fast: Performs optimization as quickly as possible, though results may be less accurate.
• Optimize bar: Optimizes bars based on specific lengths defined for each profile, ignoring standard profile length. See also Section 1, Profiles Archive, with .
• Length: When cutting multiple structures with many bars of the same profile, reduces cutting time by grouping similar lengths.
• Single length: Similar to the previous, but fully groups lengths into identical values.

• List: Optimization based on values from the list stored in the profile archive.

Bottom buttons

• : This button allows you to specify the functions that must be printed in the processing sheets, such as cutting list, optimized cutting, etc. Normally all are considered. You will need to deactivate the checkboxes corresponding to the functions that you do not want to be considered.
