The Autocorrection program
The milling path corrections cutout in 2D and 3D are centralised in the Autocorrection program. The determination of the correction direction inward or outward takes place through the setting inward/outward. For this correction the data are used in the current working area ActLayer.
Input of the tools and technology data for the calculations. A changing station (WSt) must be specified for each tool, independent of the geometry data. Tools with WSt = 0 are disconnected. A tool change is carried out only with change of the WSt#. On the other hand, tools with the same geometry data, but different technology data (milling depth, feed,…), can have the same WSt#. In this case no tool change is carried out but the technology data are changed.
A detailed description of tool input can be obtained in the General Instructions under Tool input.
This function calculates 2D milling paths and 3D cutout tracks for up to 10 tools simultaneously. The function demands error-free, closed contours without crossovers. Tools with cones circumscribe the contour in 3D, cylindrical tools (FWi = 0°) in 2D. The tool path calculation takes place by block. With this, more favourable milling paths and shorter calculation times result.
The data input takes place in the light coloured fields.
The tools are entered in the list consecutively starting with 1 up to the largest tool, the clearance tool, with their serial number from the tool library. The number of the minimum and maximum permitted tools conforms with the process. The tool input is always to take place continuously, spaces between the tools are not permitted. The tool input takes place quality-oriented, starting with the finest tool (determines the quality of the milling). The tools are to be entered in ascending order of their tip radius (FrS).
The milling angle (FWi) should be similar or matched to the task. In any case, for a correct implementation of the program, the overall radii (Res) of given tools 1 .. 10 must be given in ascending order. The milling angles (FWi) can be entered in the range from 0 degrees (= cylindrical) .. 89,999 degrees. Other milling angles are not accepted.
The program changes into tool input using or or by clicking on to the tool graphics.
All clearance paths are joined together so far as the contours are not touching or overlapped.
Input of the hatching angle for line-shaped clearance tracks (360° < 0 <= +360°).
Width of the offset calculation for track parallel clearance processes. This value should be selected to be not smaller than the resulting radius (Res) of the largest tool.
For the case that errors result with continuous calculation, the precalculation width can be enlarged or reduced.
|Calculation in surface relief height / at base.|
|Calculation for embossed / recessed.|
|Tool tip offset.|
Correction of the tool offset calculation. The calculation can be marginally corrected using the tip offset. E.g. a task can be repeated using a tip offset in order to clear tool errors.
The tip offset can be employed in the range (smallest tip radius) up to +10mm.
Change in the parameter input. For the adjustment of the parameters comp. description in the General Instructions CAD . Input Parameter – select AutoCorr
|Tool block – tool block input.|
The tools from #50 are subdivided into blocks of 10. A block can be selected, edited, opened and saved.
The tools always commence at the start of the block (group of 10). Tools with a valid station number (>0) are taken over in the calculation list in the order of the entry into the tool library. If no tool with a valid station number is available, then at least the first block tool is taken over. Sensible entries in the tool library for a tool block using the example for the block from #50 (3 tools):
The ascending order must be observed.
Open and save the calculation settings. All settings and tools of the calculation are saved and are again available following Open for an identical or similar calculation.
|The milling paths calculated using an Autocorrection process are exported. For this goto Export – Select. With the aid of this, direct export milling data, for example for stamp, can be very productively output without detours to a machine.|
|TLayer > Targetlayer.|
The calculated milling paths are taken over in one layer. For this a target layer is to be input. With the aid of this function 2D and 3D milling data can be combined in one layer and output using File . direct mill into a project. To save in a layer select the target layer using Layer Selection.
If there is already data in the selected target layer, then milling data can be loaded into the target layer or the existing data can be overwritten.

With input without colour the perspective view takes place with height level marking. For the description comp. Menu File.|
