Resetting Tool offset after insert change is must. Because every insert has it won manufacturing tolerance.
We normally do 0.2 mm Correction in safer side. then measure and give the necessary value..
Now a days we use auto Q Setter.. On which we run the AUTO TOOL OFFSET MEASUREMENT Program for auto measure. Life become simple.
