OUTLINE

TOOL NAVI supports our customers with information and supplies suitable cutting conditions for each work material by selecting optimal indexable insert together with the optional tool.

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. H : Hardened steel 60HRC x Cutting speed standards c Feed rate Minimum and maximum feed rate settings are based on the chip

*3. N : Life based on each grade. For stable conditions 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=0.3 mm H • • • VB=0.1 mm

TOOL LIFE

Cutting speed has a large affect on tool life. TOOL NAVI is based on Taylor's equation (relationship vc x 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 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 the new cutting speed. P Grade (Steel) cutting speed coefficient values. K Grade (Cast lron) cutting speed coefficient values.

HARDNESS OF WORKPIECE

Hardness of the work material also affects tool life. Mitsubishi’s TOOL NAVI suggests cutting speed variations when hardness of the work material differs. Obtain the suitable coefficient value for each work material from the chart below. Multiply the coefficient value by the recommended cutting speed of the grade you use to calculate the new cutting speed.
