Processing method for variable depth, deep-hole drilling, chip breaking and removal

A processing method for variable depth, deep-hole drilling, chip breaking and removal, characterized by comprising the following steps:

• Step 102:
• designating a deep-hole drilling variable, and assigning a value to the variable involved in the deep-hole drilling, if the value is correct, enter into step 103;
• if the value is not correct, enter into step 104 for alarming and reassigning the value;
• Step 103:
• drilling a first hole depth;
• Step 105:
• determining whether the first hole depth is greater than that of a terminal drilling depth, if yes, enter into step 106, otherwise, enter into step 109 to complete last drilling depth, and stop at step 110;
• Step 106:
• determining whether the first hole depth is greater than a defined chip breaking depth, if yes, enter into step 107 for chip breaking;
• otherwise, enter into step 111;
• Step 111:
• processing to a currently designated drilling depth and returning to a safe position for chip removal;
• Step 112:
• determining whether the currently designated drilling depth is greater than a smallest drilling depth, if yes, enter into step 113;
• otherwise, enter into step 114 to designate the currently designated drilling depth as a new smallest drilling depth, enter into step 108;
• Step 113:
• decreasing the drilling depth progressively according to a designated drilling depth proportion, enter into step 108;
• Step 108:
• calculating the coordinate of next drilling depth, return to step 105 for determining.
