· The main purpose of Gpilote is to machine files generated by CAML software "GFAO".

· The execution of this procedure is explained to you at the end of exercise N°1 of the user manual.

· You can also, with Gpilote, execute ISO Files coming from other CAM. To do this, start the Pilot, load the files to be machined and follow the same procedure as for a native charlyGRAAL File.

We present you here the mode of automatic use that is going to simplify your work.

· This first use takes some time (about 1 hour) but, don’t worry, you will not have to come back to it (unless in case of changing the sensor position).

· General principal.

Axes are configured according to the standard ISO :

In order to realize flat machining with uniform cuts, as well as constant depth engravings, it’s recommended to setup and surface a martyr plate.

Martyr plate presents 3 advantages:

· As its name indicates, it is going to support the machining overtaking, particularly, drills and cuts with conical tools.

· Since surfacing is carried out with the machine, it permits to get a perfectly rectified plate.

· With the use of integrated surfacing in the GPilote , we get natural stops perfectly positioned at points X0 and Y0.

Martyr plate must be carried out in a soft material (PVC or other, - available as an accessory -) of 10 to 20mm thickness). These dimensions must, in no case, surpass those of the aluminum machine table.

It will be fixed on the machine table either by bolting, using screws and bolts provided, or with double-sided adhesive.

Start GPilote (Start menu, GRAAL, and click on GPilote button).

Click on the control panel button Then click "OK" on the messagebox: "Machine origine positioning is going to start !"

The machine moves to the origine position (MOP).

Set the surfacing tool then switch on the spindle by clicking on the button «spindle on».

With the manual displacement buttons, put the tool tangent to the martyr plate.

When tangent click the button "ZWO". A messagebox asking if you use a tool sensor appears. Click "OK". Click "Validate workpiece origin (WO). The spindle stops and returns to its Origin Position ; return to the G-Pilot window.

Click on the menu «Machining».

Click on the «surfacing» control

Machining area of your machine, You can enter the dimensions (2) of your martyr plate if it is smaller than the machine plate.

Click on the «Generer» button.

A window appears, click OK

Validate the depth, click OK

Validate the window specifying that there is no tool in the file.

Warning: make sure that you have set the right tool and adjusted the spindle speed on the red color.

Click on the green button

Once the surfacing operation is finished, we are going to install and parametrize the tool sensor.

There is no obligation on the tool sensor position. However, we propose 2 possibilities:

Position 1

The sensor is placed under the Machine Origins (MOP), this saves the robot unnecessary displacements.

Position 2

The sensor is placed in the right upper angle of the «surfaced» martyr plate. This allows having more clearance on the Y travel.

! Precaution:

The sensor parameter setting consists in making two measures, one on the sensor and the other on the martyr plate ; it is to inform the software on the level difference between the contact of the sensor and the martyr plate level.

The fixing mode of the workpiece on the martyr plate being double-sided adhésive, we advise you to make the second measure on the double sided adhesive fixed on the martyr plate. It is to declare the Part Origin at this height.

On the main windows, click on the control panel icon.

Through displacement buttons (3), place the tool above the double-sided, then go down until it touches this double-sided (use the continuous displacement modes, then incremental, so as to perform this operation as precisely as possible).

Once the tool marks the double-sided without crossing it, the position is reached . Click on «Z WO» (4).

The operator sets a tool T1 (example: engraving tool).

The user clicks the tool measure button.

The spindle goes down and upon contacting the sensor, the spindle is in position Z = 40.00 (example).

By convention, we note this value zT1 = 40.00

Fig.3

The user touches the plate (on the double-sided adhesive). When the tool is tangent, the spindle is a Z: 12.0, So Z WO1 (Z workpiece origin with tool N1) equals 12.

Z WO1= 12.0

Fig.4

The user loads a file with a workpiece value e = 20,00 mm. The pilot corrects automatically the Z workpiece Origin to place it on the upper face of the workpiece. Consequently Z WO1 = WO1 1+e, therefore Z WO1 = 12,00+20,00 = 32

Fig.5

The user sets a tool T2 (a milling tool for example). «d» is called the length difference between tools T1 and T2.

Fig.6

The user clicks the measure of tool T2. In touch with the sensor, the spindle position is Z = 43,00. The pilot deduces that tool T2 is 3mm longer than T1.

D = zT2 – zT1 = +3 mm.

Fig.7

As the file is always loaded, the thickness of the workpiece is always active. Consequently, Z workpiece Origin with tool T2, to machine on the high side of the part is :

ZWO 2 = ZWO 1 + d = 32,00 + 3 = 35,00
