Settings tab
Use this tab to set defaults values for the tooling system.
NOTE NCeXpress specifies the overlapping of tools using two different references.
1. Minimum percentage of utilization
2. Percentage Tool overlap (minimum overlap between two hits)
Though both of these values accomplish the same task they are used to balance each other out. Hence, if the
‘minimum % of utilization’ is 10 % the corresponding ‘percentage tool overlap’ will be 90%.
Extension Factor – the amount of tool overlap at the corners. A negative value means tabs will be
left at all outside corners. This is for all external contours.
Overlap Length- unit value for minimum tool overlap
Allowed outside shape extension- Maximum allowable amount tool can overlap outside part.
Scallop Height – the maximum allowable scallop height. This factor is used to determine the
minimum number of hits by a round tool on an arc segment.
Vertex Tolerance – the maximum allowable length of a corner slug. Gives a maximum value for
an un-tooled section.
Waste Factor – the relative importance placed on saving waste material as compared to saving
strokes. Increasing this factor, while keeping the strokes factor constant, reduces the waste
material.
Strokes Factor – the relative importance placed on saving the number of strokes as compared to
saving waste material. Increasing this factor, while keeping the waste factor constant, reduces the
number of strokes required to punch the part.
Minimum % Tool Utilization – the minimum % of a tool removing material. This value must be
set for all 6 regular shape. Round, Rectangular, Square, Obround, Filleted Rectangle, Filleted
Square.
Single Hit Tolerance – the tolerances for matching tools with features. Values must be entered
for Round, Obround, Rectangle Length, and Rectangle Width. These values will determine a
substitute tool if correct tool is not found. Substitute tool must fall within tolerance values.
