CNC Program - Corner Radius Definition                                             Programming Data (mm)
The use of common CAD / CAM systems requires a
round insert dimension to be known for cavity machining.                       Insert size (mm) Radius      R  L
This is available with 7792VX cutters as shown to the
right and in the reference table.                                              06 0,80 1,37 0,40

Calculation of the average chip thickness in relation with the D.O.C. (Axial)

Formula: Programme Feed Rate (fz)  hm	 =	Average chip thickness  Formula: Average Chip Thickness (hm)
                                   ap	 =	Depth of cut
fz = hm x          d               fz	 =	Feed per tooth                        hm = fz x                ap
                   ap              d	 = 	Insert diameter 45mm                                           d

                                   Theoretical Diameter for all high feed insert sizes = 45mm

Calculation of the average chip thickness in relation with the ae (Radial Engagement) if ae is less than 50% of Dia.

Formula: Programme Feed Rate (fz)  hm	 =	Average chip thickness  Formula: Average Chip Thickness (hm)
                                   ae	 =	Radial engagement
fz = hm x          d               fz	 =	Feed per tooth                        hm = fz x                ae
                   ae              d	 = 	Cutter diameter                                                d
