Q Q(cm 3 /min)=ap(mm) ae(mm) vf()/1000 ae NoteThis table shows general conditions for shoulder cutting. Conditions should be adjusted according to machine rigidity and tooling, workpiece condition, etc. To prevent tool damage due to chip clogging, always use a chip removal method such as an air blower, etc. Since there is a danger of discharged chips flying up and causing cuts, burns, or damaging eyes, during use be sure that protective covers are in place and that workers wear protective equipment such as protective goggles to create a safe work environment. Please note that the JS coating does not cause a reaction in conductive touch sensors. Replace inserts at an early stage to avoid breakage due to excessive use. The following equation can be used to determine the metal removal rate per unit time Q: Q(cm 3 /min)=ap(mm) ae(mm) vf()/1000 This tool is not suitable for slotting. Be sure to supply a water-soluble lubricant when machining titanium alloys. FT breakers are medium-finishing inserts. Recommended for use for ae<3mm. 5

Cutting performance Features and Applications of Insert Selecting the appropriate breaker enables appropriate machining for various applications. Low cutting force, general-purpose type; First recommended Nicked inserts N2 N3 Nicked inserts enable low-resistance machining. It has low resistance machining and suppresses chatter vibration even for deep cutting. For semi finishing Wave-edged inserts FT Enables shallow-depth, high-feed-rate machining. Use of a wave-edged flute shape improves insert tip strength. For titanium cutting Sharp-edged inserts RS The sharp-edged insert is suited for high-efficiency machining of titanium. Sharp cutting edge enables machining to be performed with low resistance. Features and Applications of Cutter Body How to install the nicked inserts. The effective inserts arrangement reduces chatter vibration at heavy milling. Install N2 type inserts on insert rows with holder mark. Install N3 type inserts on insert rows without holder mark. N2 insert row The tip blade also has an insert clamping surface in the tool axis direction to achieve secure clamping. Note When using nicked inserts, install 2 types of inserts (N2 type and N3 type) on a single holder. Installing only N2 type inserts or only N3 type inserts on the holder will cause tool damage. Installing nicked inserts in the wrong position will cause tool damage. Be sure to exercise sufficient care. N3 insert row 6

Cutting Performance Since AME adopted nicked insert, it is able to reduce cutting force 30~40%. FT type Insert Nicked inserts B A Cutting Conditions vc ap ae Titanium Cutting By using a sharp-edged insert, free-cutting machining of titanium alloys has become possible. Cutting performance is also good, and good chip removal is achieved. Since machining is performed at low resistance, stable machining even at long extension amounts becomes possible and good tool life is achieved. a p a e =30 30 Chip shape comparison a p a e =10 30 Tool life comparison (Single-flute cutting) 1 chip shape AME s chip shape Maximum flank wear width VBmax (mm) 0.8 0.6 0.4 0.2 JS1025 0 0 10 20 30 40 50 Cutting scene Cutting time (min) Work material Tool model Insert model Overhang Machine used Coolant Emulsion oil (Dilution ratio: 5 to 8%) vcn Cutting speed v ffz Feed rate 7
