Lobsterback Duct Bends Sheetmetal Method

lawrie

1 0 Beginner
This is the method I use to construct lobster back bends with sheet metal tools that I can produce flat patterns from, These flat patterns can then be used to produce files for CNC profile cutting machines. I have come across other ways of doing this using surfaces, thickened and turned into sheet metal parts. The software I am using is Alibre Design. As the version I have is low on surfacing tools I have found this a good way to model lobster back bends, which I have been involved with the design and manufacture for many years.

Z Heights Skim and Plunge distance provide variable control of rapid move heights within a component. These operate in conjunction with Safe Z and Start Z to minimize slow and unnecessary movement of the tool in fresh air while machining the component form. Skim distance – An incremental distance above the model at which rapid moves occur from the end of one tool track to the start of the next. The tool rapids across the model clearing the highest point along its route by the Skim value. Plunge distance – An incremental distance above the local component surface where a downward rapid movement of a tool changes to plunge rate.

Links To provide for more efficient movement of the tool across the component the link moves that connect adjacent tool tracks can be defined in several different ways. Short/Long Threshold - This defines the distance limit up to which the Short - Links apply. Any move from the end of a tool track to the start of the next, which exceeds this distance is defined as a Long - Link move. For Short links the available options include Safe Z, Incremental, Skim, On Surface, Stepdown, Straight, and Circular Arc. For Long links the available options include Safe Z, Incremental, and Skim. Safe links apply only at the start and end of a toolpath the available options being Safe Z, Incremental, and Skim. For applications where a machine control system will permit arc fitting of rapid moves the Arc Fit Rapid Moves box can be ticked along with a suitable Radius based on the active tool diameter TDU (Of particular benefit to High Speed Machining). •Activate the toolpath 1_1 created earlier in the Leads section. •Set the Leads In and Out to None, if not already set. Press Apply.
