explain up milling and down milling

good job

When maching very hard materials is it better to use grinding or turning/milling

grinding

straight or helical teeth in slab milling will result in an oblique cutting action.

helical

A small shear angle means a ? cutting force

high

are trees a composite

i suppose

decrease in cutting speed will___ the tool life

injection

whats not true about EDMa) low material removal rateb) long time to preparec) workpiece must be conductived0 can cut only one hole at a time

it can cut many holes

in solid state welding the temperatures at the welding interface will or will not exceed the melting point of the workpiece material

it will not

poly wood is what type of composite(fiber, particle, laminar, flake, filled or none of the above)

laminar

The ? the rake angle the sharper the the cutting edge.

larger

thermal cutting will produse more or less accurate tolerances than turning/milling

less
