![]() With repetitive flycutting, a spoilboard typically needs to be replaced with a new one after 20 or 30 days.Īdditional techniques for optimizing vacuumĮdge Sealing: Since vacuum can leak out from the edges of the spoilboard, you can also consider sealing the side edges of a new board with tape, paint or a special form of sprayed shellac that dries in a couple of minutes. This “maintenance flycutting” may need to be done twice a day, especially if you are working with small pieces. Fortunately, when you have an automated machine, it picks up the right tool for flycutting and handles the job for you quickly and easily. As they become more numerous, these grooves can compromise the table’s perfectly flat surface, and the vacuum’s ability to hold down the next run of parts.Īt this point, optimizing vacuum requires a second step: flycutting your spoilboard again. ![]() But grooves often left from 0.1 mm cuts on the spoilboard can be a problem, especially when you have different runs with vastly different nesting. Programming the router to cut 0.1 mm in depth is what it takes for parts to be cut and divided correctly. When you are working with nesting cells, bolting the spoilboard to the table ensures that the sweeping arm that pushes the parts forward can’t displace it. This flycutting makes the board open and porous enough to accept the vacuum. 5 mm flycut on both sides of the raw MDF. The first step in optimizing vacuum is to make a. But raw MDF comes sealed, preventing vacuum from passing through it. An MDF spoilboard is instrumental in creating a table that is perfectly flat and in providing the best cutting surface. The integrity of the phenolic table is protected by a spoilboard made of MDF, typically with a ¾-inch depth. CNC routers can have 2-to-8+ zones to help optimize and isolate vacuum. Instead of creating suction where it is wasted, the machine concentrates the full power of the vacuum pump exactly where it is needed to maximize hold-down effectiveness. So if you have a 5’x 10’ table, but you are working with a 4’x 8’ piece, the controller keeps the vacuum within that 4’x 8’ section of the table. By accessing holes in the phenolic surface and the grooves between them, the vacuum pump under the machine can spread vacuum suction evenly around the table or through specified zones. A phenolic table’s matrix is essentially a rubber gasket that can be used to isolate the zones of the table you need to use. Optimizing vacuum starts with understanding the advantages of having a router with a phenolic table. Optimizing machine performance depends on knowing what it takes for vacuum-pumped air to permeate your machine’s table and the MDF spoilboard that protects it. ![]() Dependable hold-down capability is crucial to all jobs, but especially those that involve cutting smaller parts. Manufacturers that work with nesting CNC routers depend on optimal vacuum to hold down their parts firmly and consistently. Special thanks to Tory Martin for introducing me to Flycut last summer.How the Right Spoilboard Prep Optimizes Vaccuum It is available in the Apple app store, or you can find it on github. (10/10) Once you get used to working with Flycut you’ll never want to stop.įlycut is an open sources app. ![]() It may not be necessary for everyone, but it is an integral part of my workflow. (9/10) Sometimes I wonder why Flycut isn’t built right into OSX. (8/10) Flycut is so simple that it's beautiful. It saves me time and makes developing and writing much easier. Rating: simplicity, usefulness, beauty and necessity ![]() If you don't code, it can still be a useful tool for writing, researching, or just browsing the web. Flycut was created with developers in mind. If you work with code, this functionality will save you tons of time. ![]()
