FOCUS ON CAD / CAM
Marc Löhmann only needs about half an hour with Logopress to produce a strip layout that is sufficient for the quotation , even for more complex parts . ( Source : Logopress ).
Die templates
In the die templates , all elements ( from the plates to the columns and bushings to the dowel pins ) are stored and parametrically linked so that their positions are automatically adjusted during design changes . Marc Löhmann estimates that it takes between 100 and 150 hours to set up a die template . “ However , once a die template has been defined , then any sizes and positions are determined , the standard parts are already inserted and the BOM , as well as the drawings , are already prepared ,” he explained . the number of stations , the die length and the required stamping forces ,” summarised Marc Löhmann . However , for the final pricing , assumptions still need to be made , for example , regarding the maximum number of strokes “ but , overall , with Logopress you get a reliable quotation faster ,” explained Löhmann . He usually produces a strip layout that can be used for costing quotations in less than half an hour .
Die design and die templates
After validating the final strip layout , including all cutting and forming punches , the German manufacturer outlined the advantages of the die templates during the final die design stage with Logopress ® DieDesign . These enable the creation of die frames and all their components according to given specifications , which can then be saved and used as a basis for new die designs .
“ We have developed specific standards in our company regarding how we want to build dies . We define these standards with the die templates ,” commented Marc Löhmann . “ For example , if we have always used four M8 x 50 screws in the die template for plate fastening , then that will be the case in every one of our dies and no-one would ever think of doing it differently on their own without a reason . That ensures consistency in design and prevents any errors .”
Löhmann uses the die template as the basis after designing the strip and the corresponding punches of the die .
“ It is very important that the standard parts and the die templates work hand-inhand to guarantee a standardised die design . We always use the same plates , the same standard parts and the same set-up . In this way , you have a standard that works but from which you can deviate if necessary . The result is a huge reduction in workload and time saved in the design process ,” he added .
Once the strip layout is in place , the complete die can be assembled within a few days using Logopress .
Die testing
Marc Löhmann checks the functioning of the die design with Logopress ® DIE DEBUGGER .
“ Even for an experienced designer , it is difficult to keep track of all elements and possible collisions ,” he explained . The module automatically checks whether all screw holes are included in the CAD file , whether the hole punches are

correctly positioned or whether the scrap falls correctly . Even more important is the dynamic simulation of possible interference between die elements or with the strip .
