![]() ![]() RingsĪlso find widespread use in inlay pocket cutting where relatively large diameter cutters are used to "hog out" basic shapes, followed by much smaller diameter finishingīits that clean up the edges, sharpen the corners and add fine detail to the finished part. This is especially helpful with micro-tools where "touching-off" on some reference surface to calibrate the tool height can damage or break the tip of the tool. If all of the tools in the programmer's magazine haveīeen fitted with depth setting rings, an automatic tool changer can load and unload tools with the tip of each one the same distance from the face of the collet. The depth of cut will be as expected and will remain the same no matter how many times the tool is changed. Knowing this distance, the programmer can plunge the tool, confident that Helically ground with a positive rake and engineered with large pilot diameters, these tools provide unmatched strength and consistent performance. If the shank-side of the ring is pressed against the collet when the tool is loaded, the tip of the bit will be a known distance Corner Rounding End Mills-Helical Flute-3 & 5 Flute-High Performance Achieve outstanding performance and superior part finish with Helical Solutions Corner Rounding End Mills. The shank side of the ring (top side in the picture to the right) is accurately positioned ( d ☐.004 in.) How do they work and why would I want them? Most of our 1/8" and 1/4" shank tools are available with and without depth setting rings. With precision control of all aspects of the speed (RPM), feedrate and tool engagement empirical techniques can be used to develop cutting protocols that are both reliable and consistent across a wide range of material. However, what automated systems offer to both amateur and professional woodworkers in terms of virtually total control of the machining process, more than makes up for this loss (in my opinion). For years, experienced woodworkers have relied on the feel of vibrations in the timber and the sound of the teeth eating through the wood to tell them when the sharpness of the tool, the RPM and the feed rate were working together to produce the perfect cut. The second challenge, is the loss of tactile and auditory feedback. This has been largely accounted for through advancements in tool design, improvements in tool steels / carbides, and adaptive software that can maintain cutting properties through a wide range of wood densities. The first, and foremost, is the wide variability of cutting properties that can be encountered along a single piece of lumber. ![]() ![]() The precision machining of wood, while fairly straightforward and well understood, presents a number of challenges to CNC operators that are not encountered when doing everything by hand. ![]()
