Defect maps

Infor MES uses defect maps to represent the good and bad areas of a product that is typically a rolled up form. It is useful in processes that create a length of continuous material, where the manufacturer cannot remove the bad areas during the manufacturing operation.

These are some common examples:

  • Coated reels (length and width)
  • Printed reels (length and width)
  • Cables (length only)
  • Laminated sheets (length and width)

Defect maps describe the position of a defect in a one dimensional, two, or three dimensional sense, such as:

One dimensional
  • Distance into the inventory pack of the defect
  • Length of defect
  • Type of defect
Additionally, the defect map can determine this information:
  • Overall length of an inventory pack
  • Quantity (count and sum of the length) of defects on an inventory pack
  • Quantity of good material on an inventory pack(in length)
  • Yield = Good Length / Overall Length
Two dimensional
  • Distance into the inventory pack from one side, in the same unit as the length
  • Width of the defect, in the same unit as the length
Similar to one dimensional, the defect can determine this information in two dimensions:
  • Overall area of an inventory pack
  • Sum of the areas of defects on an inventory pack
  • Area of good material on an inventory pack
  • Yield = Good Area / Overall Area
Three dimensional
The position, or layer, of the defect in relation to the surface of the material
