Spindle stop accurately
Since tool installed on the spindle, cutting torque transmited can't only by bole-hole's friction, so there
are one bolt at ahead of the spindle, when tool installed to spindle, the keyway of tool head must match with
the bolt of spindle, and then can finish tool change, so spindle require stopping accurately at a fix angle, this is
the purpose of spindle stop accurately

This code is corresponding to the flow chart ―spindle accuracy stop‖ and make sure the spindle stop accurately.

Above program is for machine move to X and Y axis tool changing point , ready for tools back to tool
magazine, this is corresponding to work flow chart ―Spindle at the point of X/Y axis tool change‖

Above program is simple and clear, for judging the return tool number is 0 or not , Z axis position to tool
changing point , and then push out tool disc, next step is checking and waiting for disk air cylinder back input
signal, when get this signal means handle on the spindle was block in tool disc already, and then output spindle
air cylinder push signal to loose tool handle, G04 P300 delay is make sure that there is
the tool, ―G01 Z[#403+2.5] F1000‖, this code is add base on customer's tool magazine, not necessary for all
tool magazine. After getting the spindle air cylinder push signal
tool changing.
choose tool nearby
