Cutout circular stamp
Create cutout stamp.There are several conditions to be observed for automatic calculation of error-free milling paths (cutout paths) using TTrack . AutoCorrection:
Create program. Should there still be data of the last work in the program, then save these using File . Save or Save under. After this delete all the data memory using File . New. Load data. Load the file AHSoft.SLD (or another suitable graphic) using File . Open.
Calculation of milling path. Select the layer with the graphic data, here Layer 0. Select TTrack . Autocorrection . ACorr2D3D and select the setting according the figure Autocorrection 2D/3D. Suggestion for a tool application in brass (MS58).
Settings for Autocorrection 2D/3D.
Export milling data. You can issue the milling paths calculated in Autocorrection directly without detours using TLayer Export. The program opens the export menu. Select for example, DIN/ISO here. View DIN/ISO data. You can view the saved DIN/ISO data using the Texteditor. For this select Extras . TextEdit. Select the generated DIN/ISO file and open it with OK. |
Cutout circular stamp.
There are several conditions to be observed for automatic calculation of error-free milling paths (cutout paths) using TTrack . AutoCorrection:
Adjust program. Before calculation the data should be appropriately available or must be reworked using the program functions. For a circular stamp it is sensible to place the processing zero point centrally. Adjustment takes place using Layout . Limits. Note: An existing graphic (e.g. imported data) can be placed centrally very easily using centre frame and centre graphic. Inserted graphic. The imported graphic AK (from DXF) consists of a series of individual curve segments which have to be combined. This is a typical image for DXF data, which have been saved using lines and arcs. The import of DXF data is always to be viewed critically. Unfortunately DXF, as pure character format , takes no notice of possible processing. The graphic must be converted into closed contours using process . Combine tracks. For join tracks, the setting close up to error = 0.000 mm is sensible for general work. This automatic process attempts, over several steps, to join line segments into closed contours. It is only when the data contains larger errors (crossovers, overlapping, gaps > 10mm), that the process fails and the remaining paths must be joined manually. The paths can be joined in the menu edit (join posn). Font. For a milling offset calculation an outline font is required. Outline fonts in HCAM../iSIGN+3D are all fonts, which begin with F.. or imported TrueType-/ Type1 fonts. Here the font F1000219.HZE(DIN1451 mean) has been used. This typeset has a very small surface relief width and is suitable for special marking stamps.
Milling path calculation. The milling paths are first calculated for a flat 3D stamp. The projection on the cylinder takes place later with data export. For the milling path calculation select one after another Layer #0 and TTrack . AutoCorr . ACorr2D3D. 3 tools were selected for the calculation: #50 (FrS = 0.02mm); #51 (FrS = 0.08mm); #52 (FrS = 0.2mm). The tools are loaded in ACorr2D3D . Tool-Block from the file CutoutTool.ToolWZB. Tools: 1 = #50; 2 = #51; 3 = #52. Automatically adjusted with loading of the tools in Tool-Block . open.
Following the calculation the milling paths are presented in the tool colours. You can monitor the milling paths using TLayer MillGraphic . Graphic MillingTrack.
In Zoom TLayer MillGraphic it can be seen clearly which parts are reached (processed) using the individual cutter radii:
Data export. The milling paths calculated for a surface stamp can now be exported to the machine. There are 2 paths available for the data export:
