13. ITNC 530 to extract contours Not only does this save time otherwise spent on programming and testing but you can also be sure that the finished contour is exactly according to the designer s specifications with which the designer organizes the drawing So that as little unnecessary information as possible appears on the screen during selection of the contours you can hide via mouse click all excessive layers contained in the DXF file This requires the keyboard with touchpad or an external pointing device The ITNC can select a contour train even it has been saved in different layers The DXF format particularly the DXF format supported by the ITNC 530 is very widespread and is supported by all common CAD and graphics programs After the DXF file has been loaded onto the ITNC from the network or a USB stick you can open the file just like an NC program in the iTNC s file manager Meanwhile the ITNC considers the operating mode in which you started the DXF converter and generates either a contour program for smarI NC or a program in conversational format HEIDENHAIM 34 As a rule DXF files contain multiple layers The ITNC also supports you when defining the workpiece preset The datum of the drawing for a DXF file is not always located in manner that lets you use it directly as reference point for the workpiece especially when the drawing contains multiple views Therefore the ITNC has a function with whic
14. You can make full use of the ITNC 530 s ease of use even for offline programming 36 Programs created offline NC programs for five axis operations are normally written on CAD CAM systems The workpiece geometry is described in the CAD system while the required technology data is added in the CAM system The technology data specify the methods such as milling drilling or boring the strategy area pocket clearance plunge milling etc and the parameters spindle speed feed rate etc for machining the workpiece A postprocessor uses the geometry and technology data to create an executable program which is then usually transferred over the company network to the iTNC 530 In principle postprocessors generate two types of NC programs both of which can be run by the ITNC 530 e Machine specific NC programs take the respective machine configuration into account and include all coordinates of the NC axes on that machine e Machine neutral NC programs define the contour and use vectors to define the respective tool position on the contour The ITNC 530 then uses the information to calculate the axis positions of the actual machine axes The key benefit here is that you can run such NC programs on various machines with differing axis configurations The postprocessor is the link between the CAM system and the CNC control Standard features on all prevalent CAM systems include post processors for DIN ISO format as w

Subcontours can be pockets or islands Different components are combined to form a single pocket in which the tool circumnavigates the islands You can assign a separate depth to each subcontour If the subcontour is an island the ITNC interprets the depth entered as the height of the island You can also program open contours with the SL cycles This enables the ITNC 530 to observe allowances for 2 D contours to move the tool in alternating directions after each infeed to avoid contour damage at undercuts and to maintain the defined milling direction climb or conventional after coordinate transformations such as mirroring OEM cycles As original equipment manufacturers OEMs machine tool builders can contribute their special manufacturing know how by designing additional fixed cycles and saving them in the ITNC 530 However the end user can write his own cycles as well HEIDENHAIN makes this possible with its PC program CycleDesign CycleDesign enables you to organize the input parameters and soft key structure of the ITNC 530 to suit your own needs 3 D machining with parametric programming With parameter functions you can program simple 3 D geometric figures that can easily be described mathematically Here you can use the basic arithmetical operations trigonometric functions roots powers logarithmic functions parentheses and logical comparisons with conditional jump instructions Parametric programming a
