mediate step, offers great fl exibility and a wide range of possibilities for the fabri-
cation of complex shapes (Figure 11.8). It allows effi ciently producing precision
complex parts with fewer operations and setups, reducing cost, waste, and deliv-
ery times.
11.3.2 Microstructure, Phase and Element Distribution
The main variables distinguishing different species of woods are the types, sizes,
and distribution of cells. Due to seasonal growth rate changes, these variables also
