9.3.1.5 Notching blades

Notch tools are used for cutting easy and precisely alignment notches. The chisel
blade can cut ‘V’ shape and slit notches. The depth and orientation of the notch
varies.

9.3.1.6 Marking tools
Marking can be done via pen, inkjet, ink spray, or stick-on adhesive label marking
tools integrated in the cutting head of the cutter or fixed in the marking toolhead on
a separate gantry. Marking tools are used to identify cut components for subsequent
processing (see Section 9.3.7).

9.3.1.7 The cutting device drive system

Two synchronized servomotors move the gantry along the length of the cutting table
(the X-axis), while the third servomotor moves the carriage on the gantry across the
width of the cutting table (the Y-axis) (see Fig. 9.11), and the fourth rotates (the C-
axis) the cutting tools during the cutting process. If the cutting tool (an oscillating
knife; see Section 9.3.1.3) also moves vertically (the Z-axis), an additional motor is
used to complete the cutting process. The cutting process can be carried out at variable
speeds, depending on the properties of the material, the complicity of cut contours and
the specific requirements of a cutting operation.
