Work Specification Approach Movement

Lettering using cutout paths, inclined approach movement into the material and layer processing.

3D Approach movement.

Inclined engagement movement into the material and layer processing developed by eSIGN

Through the simple, intuitive operation, handling of eSIGN requires no special instruction. Nevertheless, the program is very comprehensive and high capacity. Therefore, in order to familiarise yourself you should read through the General instructions CAD and the instruction CAD Design. If you have questions on operation please first use the program help. With already activated functions you can access these using  or using aid program help [?] and click-on the function.

Description of the functions to be selected.

In the following description a short notation on the selection of functions is employed. The domains are respectively separated using a dot ‘.’, e.g. CAM . Rate of cut preparation. You will find the function in the  CAM menu under Rate of cut preparation.

The approach movement.

Using the function CAM . Rate of cut preparation 2D and 3D milling paths can be furnished with approach movements and takes place in layers. The function is always to be used on milling paths only and is to take place following an offset calculation. For the selection of the function please select the program help.

An inclined approach movement is created for an incision angle of 10° .. 89°. An incision angle of  90° allows the inclination movement unchanged vertically downwards. The approach movement always takes place on the existing milling paths as serves mainly for tool relief (prevention of tool breakage with incision). For extremely short milling paths (e.g. point, short vector,..) possible no or only very steep approach movements are created.

Example: milling paths from a rectangle, incised calculation with incision angle 30° and three milling layers. Total milling depth = 5.0 mm.

Milling paths for the example ‘Happy Birthday’.

The 2D graphic in  Layer #0  is worked out (cut out) recessed using a spherical tool. Data of the tool i.a.w. the graphic.

The milling path calculation takes place using CAM . MillCorr 2D/3D (see example). The milling result is saved in the  Layer #16 .

The calculated cut-out paths have a max. milling depth of 4.589 mm (first indication for layer depth in the rate of cut preparation. The layer depth is selected at 2 mm (adjustment comp. graphic rate of cut preparation). This produces three milling layers (2.0 mm; 4.0 mm; 4.589 mm comp.  Layer #17 ).
