The 1st question is about the “offset value” when creating the tools.
a. By default, the offset factor when creating the tool is 1.2 (gap =1.2*blank thickness)
a. 20% offset pattern (total gap will become 1+0.2),
for example, your blank thickness is 1 mm and tool offset is 20% total gap will be blank thickness+20% of blank thickness =t(1+0.2)
b. However, sometimes, we are provided with a full set of die tools, including the top die, punch, and binder.
And in the design, the gap is only equal to the blank thickness, for example = 1mm. So what should we do in this case?
i. Take their design faces to use as tools, with the gap between die and punch = 1mm
you need a little gap here
ii. Recreate the punch by offsetting the die face >> gap = 1.2 mm (as above)
this can be done easily using the offset tool.
2. The 2nd question is about the material density in HyperForm and InspireForm.
Take an example for steel, rho = 7.8e-9 (ton/mm3)
If I use the uniform mesh size (turn off adaptive mesh), the density is remained originally = 7.8e-9 t/mm3 However, when using both InspireForm or HyperForm with the “adaptive mesh = on”,
The rho is increase 10 times >> new rho = 7.8e-8 (t/mm3)
2. Check over the unit consistency and compare the model
