Machining allowance has a great effect on the machining quality and production efficiency. The overlarge machining allowance will not only increase the machining workload,but also lower the
production efficiency, increase the consumption of material, tools, electricity and add to the machining cost. On the contrary, if the machining allowance is too small, it will not eliminate the
defects and errors of the last process and also can't make up the clamping error in this machining process, so that it' will make a waste. The selection principle is that we should make the allowance
as little as possible on the premise that the quality is up to standard. Generally, the more precise process, the less machining allowance.
