Lightweight humanoid robot housings put pressure on both structure design and machining stability. The domestic article discusses how material choice, wall thickness and cutting sequence change the result.
Al7075 can support strong lightweight housings, while engineering plastics such as PEEK need different temperature and clamping considerations. Both should be reviewed before prototype production.
A useful article page for overseas buyers should explain material behavior, fixture method, roughing strategy, finishing allowance and inspection planning in one clear route.
