Remnant Plate Generation

This fully automatic true shape nesting software enables nesting of a variety of features.
NOTE: This is an optional advanced module and needs to be licensed separately.
Depending upon the nature of the parts and sheets, some area in the sheet is left unutilized. If the information about the unutilized area is provided to the user, then user can use the same again for nesting the parts. This unutilized area that can be used by the user again is called remnant plate.
The shape of the remnant desired is depends mainly on the type of the material and the cost incurred and the expectations vary from customer to customer. Hence, options to select the type of remnant is provided to the user. Remnant plate generation module generates following type of remnants depending on the criteria set by the user:

This module is an Optional advance module and needs to be licensed separately.

Clean Cut Remnant
The Clean cut remnant type seeks to get the best possible remnant by drawing a vertical/horizontal line where the parts stop nesting further on the sheet.

Rectangular Remnant
The rectangular remnant type seeks to get the best possible rectangles from the remnant sheet obtained. The rectangles so determined have any dimension not less than the minimum width specified by the user. The area of each rectangle is not less than the minimum area specified by the user.

Stepped Remnant
The non-rectangular remnant type seeks to determine a reasonably well true shape remnant sheet. To find the remnant, it uses the bounding boxes of the parts instead of its true geometry. It gives a reasonably good remnant quickly for most of the cases. The area of each remnant sheet found is not less than the minimum area specified by the user. Also its dimensions are not less than the minimum width specified by the user.

True Shape Remnant
The true-shape remnant type seeks to determine the remnant of true shape. It uses the true part geometry for the purpose. The area of each remnant sheet found is not less than the minimum area specified by the user. Also its dimensions are not less than the minimum width specified by the user.

A typical remnant plate generated when different options are selected is shown below:
The remnant generation module in NestLib provides a facility to the user to automatically generate the remnant plates once a sheet is nested. These remnant plates can be stored in the inventory database and can be queried for nesting purposes before using a fresh sheet.

Key Features:
  • Option to select the shape of remnant plate
    • Clean Cut – Gives end-to end cut (guillotine cut) from nested height
    • Rectangular – Gives the remnant in rectangular pieces
    • Stepped – Gives the remnant in rectangular steps
    • True Shape – Gives the true shape of the remnant
  • Option to generate remnant on the last sheet only
  • Option to display only specific remnants

Benefits:
  • Reduce wastage of material and generate revenue
  • Better management of material cost and inventory
  • Eliminate manual work for nesting and cutting the remnant sheet
  • Options enable the user to select based on precision and speed of operation
