TOOL NAVI I OUTLINE TOOL NAVI supports our customers with information and suitable cutting conditions for each work material by selecting an optimal indexable insert together with the optional tool. I LABEL INDICATION CNMG120408-MP MC6025 CNMG432MP QU691NZ1AM3B9 vc 310-190 m/mln A p 1015 - 625 SFM v< If 0.16 - 0,50 mm/rev c V 0.006-0.020 IPR Vj MADE IN JAPAN 1 The above is an example. There may be inserts recommended for multiple work materials. 2 Please contact us for recommended cutting conditions using coefficient values other than the above.

N :Life based on each grade. For stable choose the performance cutting speed and for unstable choose the tool life feed rate. 4. The tool life is based on the following (VB wear). Some materials include elements other than this. PMKS VB=0.3mm H VB=0.1mm TOOL LIFE Cutting speed has a large affect on tool life. TOOL NAVI is based on Taylor's equation (relationship vc Tn=C between tool grade, cutting conditions, and tool life). Therefore, performance speed and tool life is found for each work material. When the customer requires a different tool life, obtain coefficient values of the grade you use from the charts below. Multiply the coefficient values by the cutting speed to calculate a new cutting speed. P Grade Steel) c utting speed co< 3fficient values.

Tool life required by the customer: 30min. 310x0.83 257m/min HARDNESS OF THE WORK MATERIAL Hardness of the work material also affects tool life. Mitsubishi's TOOL NAVI suggests cutting speed variations when hardness differs. Obtain the suitable coefficient value for each type of work material from the chart below. Multiply the coefficient value by the recommended cutting speed of the grade you use to calculate a new cutting speed.
