Hello,
the objective is to create precise master patterns as a basis for UNI Mould system moulds. The pattern, moulds and ultimately parts need to be tempered at up to 85°C.
Pattern making process (you may assume for an airfoil with a span of 1.5m):
1: CNC machine pattern -0.5mm
2: apply a coating, that can me machined to 0.0mm
3: sand and polish (note: Sanding and polishing will be minimal and are only required to create the required surface quality, machining will define the shape; we talk about precision parts)
Are the Low/High Density Polyurethane Foam Blocks suitable for this process?
What coating would be recommended for step 2?
Warp has been an issue using other pattern materials - so are these products an alternative?
