What’s a Router? Before discussing or using a CNC router it is helpful to know how to use a handheld router. Photoacute studio crack llc 2017. Your typical router has a motor (possibly a variable speed motor), height adjustment (either fixed, or plunge), and a collet, which is a tapered spring that when compressed creates the friction necessary to hold your cutting tool in place. When you use a noncomputerized router you see, hear, and feel how the tool can cut with instant haptic feedback.

Then there is the fun stuff. SAE port tools usually run about 25% of what they recommend or they chatter. PCD throws out all the rules of SFM. Most of the time you can run max spindle RPM. Those numbers run pretty well for us. When we get iron or steel, we have to go back to fundamentals to figure feeds and speeds.

If you have access to one, go play with it before attempting to create toolpaths on the computer. Make a quick sketch on a 12”x12” piece of scrap plywood and use a ¼-inch bit to cut it out. If you are working with a fixed base (not a plunge router) be sure to drill a 3/8-inch hole to enable you to safely start the router in the material. Set the bit so that it cuts no more than 1/8 of an inch deep per pass, and be sure to secure the plywood to your table. Be advised that using a router bit/depth not specified could be potentially dangerous. Use a bit smaller than 3/8 inch and use a step of less than the radius of the bit. Begin the cut at the center of your shape and work out in a spiral-like pattern, this will provide support for your router if your shape is larger than its base.

As you work your way toward the sketched lines, try making both clockwise and counterclockwise motions and notice that one direction provides far more control and accuracy. What are Toolpaths? A toolpath is the user-defined coded route which a cutting tool follows to machine a part. They are represented on the screen by lines and curves which represent the path of the bottom center of the cutting tool. Pocket toolpaths etch the surface of the material, while profile toolpaths cut all the way through. Pocket The process described in the handheld example above is called a “pocket” toolpath. In your first pass you will remove everything inside your lines to a constant depth of 1/8 inch below the surface.

If you want to remove more than 1/8 of an inch simply pause after the first pass, lower the bit, and remove a second pass 1/8 of an inch lower and so on. Profile toolpaths being cut. Most CAM software provides what seems to be an insane number of controls and options in the toolpath dialogue. Don’t get overwhelmed and take your time to slowly move through each tab in succession being sure you understand all the options. The most important concepts to take away from the handheld router experiment above are: spindle speed, feed rate, step-down, and step-over.
