Normal problems and solutions for threading tools machining:

Problem	Cause	Solution
Over wear on clearance face	Cutting speed too high.	Reduce cutting speed
	Low cutting depth, abrasion.	Reduce frequency of feed and friction of cutting edge.
	Inserts are over the center line	Adopt correct center height.
Asymmetric wear on right and left cutting edge	The inclined angle of insert is different from the helical angle of thread	Change to proper shim to get correct inclined angle.
Asymmetric wear on right and left cutting edge	Flank in-feed is not correct.	Change the way of flank in-feed.
Breakage	Cutting speed too low.	Increase cutting speed.
	Cutting force too high.	Increase frequency of feed and reduce Max in-feed.
	Unstable clamping.	Check if workpiece vibrates. Reduce overhang of tool. Verify clamping of workpiece and tool
	Chip twisting.	Increase the pressure of cooling liquid to blow away chips
Plastic deformation	High cutting speed, high temperature on cutting area	Reduce cutting speed. Increase feed frequency and reduce Max cutting depth
Plastic deformation	Insufficient cooling fluid.	Increase cooling fluid supply
Low thread surface quality	Cutting speed too low. The insert is over the center line. Chips are not under control.	Increase cutting speed. Adjust centre height. Change the operation way of tools to well control chips.
Incorrect profile	Incorrect center height.	Adjust centre height
Incorrect profile	Pitch on machine is not correct.	Adjust machine.
Shallow profile	Cutting speed set wrong.	Alter cutting depth
Surface damage	Chips involved or contacted.	Change to flank in-feed to control chip flow direction
Built-up edge	Temperature of cutting edge is too low.Usually occur when machining stainlesssteel and low carbon steel.	Increase cutting speed as well as pressure andconcentration of cooling fluid. Choose inserts with good toughness
Crack on surface	Cutting force too high	Reduce the cutting depth of each feed.
Vibration	Incorrect clamping of workpiece or tool	Verify clamping of workpiece and tool. Minimize overhang of tool.
	Incorrect cutting parameters	Increase cutting speed or reduce it substantially.
	Incorrect tool clamping	Adjust center height
