Tech tables help determine cutting speeds. They use material grade, thickness, and cutting area to determine feederate.
SecturaFAB lets you edit tech tables to prevent underestimation. Imagine a machine on your shop floor is a bit older. At some thicknesses, it may run slower than the manufacturer indicates in the tech table. Let’s explore how to change feedrates to match the machine’s performance.
1. Choose the equipment that you want to edit and select “Edit.” If you need help navigating to the equipment screen, utilize “General Navigation” in the knowledge base.
2. Select the “Edit” icon next to the technology file name.
3. When editing the tech table, changes are automatically applied. These values are crucial for the SecturaFAB calculators to return a cutting speed. Let’s define the essential tech table columns.
A: Material Group or Material Grade – If your tenant includes material grades that are not classified AL, MS, or SS, you must add them to the tech table or change the associated material type to AL, MS, or SS. You can also use Column A for material grade (A36). If you use both material grade and material group, ensure the grade is listed first in the column.
C: Thickness – If you would like to add or remove thicknesses, remember that SecturaFAB rounds down when selecting thickness. For example, if an item were 0.14 inches thick and used the example tech table, the speed for 0.123 inch would be used.
E: Feedrate – This column is equipment cutting speed. Each cutting speed has a unique material grade, thickness, and area lookup associated with it.
G: Pierce Time – For every part or pierce on part with a cutout, this value is added to the total cutting time.
K: Area – Adjust area to accommodate for slower cutting times for small parts or cutouts. If a part has a qualifying cutout, two different feed rates will be used to calculate the final time. (Can either speed up or slowdown.)
4. Review any changes to equipment speed by expanding a quoted line item and selecting the three dots tab.
