Purpose: Run large FlowJet jobs quickly and efficiently with their own nesting software. Maximize your material when cutting multiple parts.
Tools: AutoDesk AutoCAD 2012, FlowNest
Step 1: Part Data
There are three areas to work in while using FlowNest, and the buttons can be found up at the top: Part data, Sheet data, and Execute. With Part data selected, you can add a file over on the left. The window that pops up allows you to import the desired file as a DXF or ORD. This can save you a ton of time with pathing complicated or detailed parts because you only have to path once, but can populate the entire field! Here you can also indicate how many copies of the part you want, and give certain priority in the event that space is limited on your cut sheet.
If at any point later on you want to change parameters for you file, click on the “Modify” button.
Step 2: Sheet Data
Now that you have your file(s) set up, the software needs to know what area is available to populate and cut from. Normally I will enter in the dimensions of the rectangular sheet that I am using and check the box at the bottom. HOWEVER, if you are reusing a piece of scrap which is now of course partially used and an irregular shape, you can specify that previous DXF file (“Save Remnant” helps in the Execute stage) and the nesting software will maximize the remaining space!
(I totally nerded out when I learned about that feature.)
Again, if at any point later on you want to change parameters, you can click the “Modify” button on the left. Additionally, if you want to return to the Part Data section remember that the button is at the top.
Step 3: Execute
Clicking on the Execute button will populate the imported file(s) within the defined area and automatically maximize the space usage. While pretty straight forward, things to note are: “Nested Quantity” indicates how many parts were actually placed on the sheet, “Demanded Quantity” is what you initially wanted, “Remained Quantity” is the difference between the first two (free math!), and “Utilization” is the area of the sheet consumed.
From here, if you need to make adjustments go back into the Part Data or Sheet Data sections. Otherwise, “Save Path” and you are ready to rock.
The series is complete (whew)! Check out any of the previous entries if you missed something, and let me know if you have any questions.
