Choose the largest diameter of the boring bar as possible, but at the same time ensure that there is enough space between the boring bar and the hole for chip removal.
Ensure that the cutting parameters used are conducive to adequate chip removal and produce the correct chip type.
Select as little overhang as possible, but at the same time ensure that the length of the boring bar can achieve the recommended clamping length, the clamping length shall not be less than 3 times the diameter of the boring bar.
When processing vibration sensitive parts, the vibration - reducing boring bar is used.
Select a primary Angle of deviation as close as possible to 90° (an Angle of entry close to 0°) to guide the cutting force along the boring bar. The main Angle of declination shall not be less than 75°. (The cutting Angle shall not be greater than 15°)
As a preference, the indexable blade should have a positive rake basic shape and a positive rake blade groove to minimize tool deflection. Choose a tip radius smaller than the depth of cut.
Insufficient cutting edge load may increase vibration caused by friction during cutting. Select a cutting edge that is larger than the tip radius to ensure a good cutting effect. Excessive cutting edge load (large depth of cut and/or feed) may increase vibration caused by tool deflection. Uncoated or thin-coated blades generally produce less cutting force than thick-coated blades. This becomes especially important when the length diameter is large. A sharp cutting edge usually minimizes the vibration tendency and improves hole quality. For inner turning, the groove type with open chip breaking groove is usually more favorable. In some processes, a higher level of toughness can be considered because it can handle any risk of chip clogging or vibration tendency. If chip formation needs to be improved, consider modifying the tool path.
