How much do you know about chip-related knowledge?

Chip type

Elements that determine the shape of chips

01)Workpiece material

Different chips form different chip shapes

Cutting speed 40m/min feed=0.1mm/rev cutting depth=2.0mm

02) Chip chute shape

Influence of front angle

Influence of chip wall position

Chip curl type

Chip section type

03) Cutting conditions

Material to be cut SUS303 Feed 0.03mm/rev Cutting depth 2.0mm

Cutting material SUS303 Cutting speed 40m/min Cutting depth 2.0mm

Summary: Methods to improve chip handling

Reduce the blade rake angle (*side effect: increased cutting resistance)

Reduce the width of the chip flute (*side effect: increased cutting resistance)

Reduce cutting speed (*side effect: working hours increase)

Increase feed (*side effects: increased cutting resistance, risk of chipping, poor finish)
