1. Apply a sufficient amount of coolant. 52
2. If cutting speed is decreased too much from above condition, chip evacuation will deteriorate.
If the feed rate is increased too much from above condition,inner edge chip evacuation will deteriorate.
If the feed rate is decreased too much from above condition, outer edge chip evacuation will
deteriorate.
3. If chips become long and are entangled with the tool
when low carbon steel cutting, increase the cutting speed to 400-500 SFM.
If this doesn't solve the problem, try peck feeding.
