STOCK REMOVAL CYCLE. YOU SPECIFY TWO LINE NUMBERS AND THIS CMD EXECUTES ALL INSTRUCTIONS WITHIN THOSE LINE NUMBERS. BASICALLY YOU'RE DEFINING THE FINISHED PART SHAPE AND TELLING THIS CMD HOW MUCH TO REMOVE WHILE FOLLOWING THE SHAPE. THE G70 CMD EXECUTES THE SAME INSTRUCTIONS ONE LAST TIME TO PUT A FINISH ON THE PART.
Term
G70
Definition
FINISHING CYCLE. EXECUTES INSTRUCTIONS WITHIN TWO LINE NUMBERS. BASICALLY YOU'RE DEFINING THE FINISHED PART SHAPE AND USING THIS CMD TO PUT A FINISH ON THE PART.
Term
G81
Definition
DRILLING CANNED CYCLE. YOU JUST NEED TO CHANGE X OR Y (ON MILL) TO REPEAT DEPTH OF HOLE
Term
G82
Definition
SPOT DRILL/COUNTERBORE CANNED CYCLE. DRILLING CANNED CYCLE. YOU JUST NEED TO CHANGE X OR Y (ON MILL) TO REPEAT DEPTH OF HOLE
Term
G83
Definition
DEEP HOLE PECK DRILLING CANNED CYCLE. DEEP HOLE IS DEPTH MORE THAN 3 TIMES THE DRILL DIA. YOU JUST NEED TO CHANGE X OR Y (ON MILL) TO REPEAT DEPTH OF HOLE. DRILLING CANNED CYCLE.
Term
