N.B.: Always follow the order of operations illustrated in the diagram below:

HOMING (after startup) ⇒ PROGRAMMING ⇒ OPERATION

First complete a correct axis homing procedure (the first screen after startup). Select a work program, that must have been programmed in the work cycle menu. Infine the work program must be performed from its specific work program menu.

The screen can be opened from any work program page, to carry out two important functions:

1. : confirm a RESTART and then an automatic cycle that was stopped by an operator input or an emergency stop. It is zeroed and at the next cycle start it starts from the beginning.
2. Press SET X, SET Y, SET Z to zero the axis in the current position.

Screen to help the operator understand where to zero the axes for each specific work cycle.
The operator can select one or both of the above operations.

MULTIPLE CUTS makes a series of cuts to obtain pieces of a set size.
10 programs are available.
For each of the two programs can memorise

• up to 10 different sizes(SIZE).
• each size can be repeated several times (PIECES).
• Tile thickness.

The screen:

	Open axis zero-setting screen
	Z depth increase for multiple stroke cutting in cut direction
	Z depth increase for multiple stroke cutting in opposite cut direction
	Final Z increase for full slab depth. The final cut is in opposite cut direction

GRID CUTS are used to cut a slab into rectangular tiles. 10 programs can be saved.
Each program memorises:

• Tile length(Y axis)
• Tile width (X axis)
• Slab thickness

Zero-set the axis positions on the bottom lefthand corner of the slab. The cut start and end are calculated automatically, according to the number of tiles and their dimensions.
Always set the correct disk diameter in Machine Setup, to obtain precise calculations.

Use only the Y-Z plane to draw and program profiles with straight lengths

• with a vertical disk
• with a horizontal disk

Never draw profiles on other planes.

First draw and program the profile with a straight length on Y-Z plane

• with a vertical disk
• with a horizontal disk

Then draw the length cutting:

• on X-Z plane for a vertical disk oppure
• on X-Y plane for a horizontal disk

To change plane just touch the drawing.

Open the Parameters Menu by pressing in the Profile work cycle programming menu.

Smoothing is NOT possible on curved lengths

	Block dimensions. The block is shown as a rectangle in the drawing window to check the block size.
	Offset. Cuts leave an extra layer for finishing.
	Cutting strategy. Cut spacing options: * D spacing along profile perimeter * D spacing along Y axis.
	Preview. Press to see cut preview .
	Repeat. The profile is repeated NP times at SP gap between one another.

	Smoothing mode selector: OFF : smoothing off CONTINUOUS: automatic smoothing after profiling. ONLY: smoothing only, without profiling.
	DX: spacing between two smoothing strokes. V: maximum interpolation speed between Y and Z axes, during smoothing.
	Vertical offset of smoothing stroke. A negative setting lowers the strokes.
	Curved lengths: enter the maximum cutting speed.

Open a work program to access one of the following screens.

Press Start and the profile roughing cycle begins the sequence of single cuts or series of multiple cuts. The X axis always moves between the two self-learned points (outside the block size).

If set to CONTINUOUS the smoothing now starts (or OFF = no finishing, ONLY = direct finishing, no roughing).

In Finishing the disk goes to self-learned minimum X point + correction and makes a series of YZ interpolated cut strokes. Finishing ends when it reaches the self-learned maximum X point - correction:

N.B. Press Start and the automatic cycle will enter the Axis zero-setting procedure on the block.

Screen showing how to position the blade flush against the block before the Z and Y axis zero-setting.

The profiling roughing is obtained by the pre-set single strokes or series of multiple strokes. The X axis moves between the two self-learned points (outside the block size) adding two horizontal sections equal to the disk radius before and after the profile drawing.

Two cases are possible:

Profile width + disk diameter is greater than the two self-learned X points. As shown, the cut starts at the self-learned minimum point and is completed when it passes the self-learned maximum X point.

Profile width + blade diameter is less than the two self-learned X points. The cut starts at self-learned minimum point. The end point is extended and adjusted to the self-learned maximum X point.

N.B. the smoothing program cycle is not available for curved length profile work cycles.

N.B. At the start of the automatic cycle, the axis zero-set procedure is entered.

The tool diameter compensation in 2D geometry work cycles determines the path a tool of a given diameter has to follow to obtain the set piece.

When the tool diameter has been set in the 2D work cycle, a preview of the tool path is drawn in blue. The operater must check the tool path is correct.

This check must verify the feasibility of paths in the following extreme cases:
