10.2 Machining operation procedure
To perform a working cycle, proceed as follows:
1. Tool the machine, following the indications given in the paragraphs below.
2. Create a program with the NC software (CAD-CAM), or open and launch an existing program
(refer to the User Interface Manual).
The operator must use the CAD program to implement the design, and the CAM program to
set the machining parameters. Then he must check the tooling is correct for the program to
be used, if necessary replacing the cutting head parts needed for the machining operation
and for the abrasive required. Refer to “Maintenance of the working head”.
3. Select the operating mode - automatic (see paragraph10.6) or manual (see paragraph 10.5).
10.3 Origin management and selection
Origins management
The point of reference of a piece, identifying its position on the work table, is called the ORIGIN.
The point of origin of a shape usually corresponds to one of the four corners of the imaginary (or
real) rectangle that encloses it; it may be freely chosen by the operator.
The choice of origin is linked to the use of the laser pointer.
The choice of the point of origin conditions the drawing (which differs according to the corner
chosen as the reference point):
LOWER LEFT CORNER (origin 1): the drawing must be formed in the 1st quadrant of the
Cartesian axes (positive X values and positive Y values)
LOWER RIGHT CORNER (origin 2): the drawing must be formed in the 2nd quadrant of the
Cartesian axes (negative X values and positive Y values)
UPPER RIGHT CORNER (origin 3): the drawing must be formed in the 3rd quadrant of the
Cartesian axes (negative X values and negative Y values)
UPPER LEFT CORNER (origin 4): the drawing must be formed in the 4th quadrant of the
Cartesian axes (positive X values and negative Y values)
