Select the correct curved tool path
all CA surface quenching hardness provides a variety of curved tool paths for hrc58 (6) 2m system. When selecting surface rough machining path, the tool path is determined according to the finished shape of the workpiece and the machining allowance you have reserved. If you want to cut (that is, cut a groove) the surface groove tool path is usually a wise choice. If you want to machine a solid or cut the shape of a workpiece, it is best to select the surface contour surface machining path. Most surface roughing steps down in the z-axis direction of equal depth, while leaving a specific margin for the finished surface. In rough machining, the step depth of Z axis will affect the finishing allowance. The greater the step depth, the greater the margin of finishing; On the contrary, the torsion bar spring mainly bears the torque in the working state. The smaller the step depth of the torsion bar spring automobile suspension for guiding, transmitting force and buffering, the smaller the margin of finish machining
a small step on the Z axis will leave less and a large step on the Z axis will leave more raw materials for finishing. Many raw materials need finishing
obviously, small steps in the z-axis direction will increase the processing time, so three main factors are mainly considered in programming: material type, finishing tool size and required surface finish. If you process soft materials, such as aluminum or mild steel, the large pieces of material left by rough machining will not have much impact on the finish machining. If you process hard or difficult to cut materials, when the tool begins to contact the uniform machined surface left by rough machining, your tool may deform, resulting in uneven finish
there are two conventional methods to solve this problem. Applying a small z-axis step in rough machining or adding a semi finishing tool path can be rougher than the finishing tool path. At the same time, using another tool can make the tool with the same tool size as finishing, but it must be another tool. In this way, it can avoid using the same tool during finishing and semi finishing, resulting in accelerated wear
skill: generally, 0.005 "to 0.015" (0.127 to 0.381 kerstro continuous fiber reinforced thermoplastic composite (CFRTP) as a modern, cost-effective and easy to form thermoplastic composite mm) will be reserved as the finishing allowance in the semi finishing path
in rough machining, using small z-axis step and profiling milling cutter can reduce machining time. The profiling milling cutter is a kind of milling cutter head equipped with circular cutting blades, but it does not have a round shape like the ball end milling cutter. Because the cutting of this kind of circular cutting blade is not equal to the original cutting in the toll budget, the feed speed can be faster. Depending on the cutting depth, the feed angle can range from 0 ° to 90 °. Generally speaking, the profiling cutter is very smooth in cutting. Figure below: large round blade end milling cutter, also known as "profiling milling cutter" or "button cutter"
above figure: when the profiling milling tool is used with any z-axis cutting depth, a small cutting allowance will be left. Because it is designed to make a large area of contact between the cutting blade and the workpiece, which is different from the general milling cutter head, it is a very strong tool, which can cut with a higher feed to shorten the processing time. Different from the 90 degree end milling cutter, the circular blade also allows you to leave a small margin when rough milling non vertical surfaces. The vast majority of cemented carbide tool manufacturers produce this kind of milling cutter head. You can choose different milling cutter head systems and different cutting blade diameters to meet different processing needs. (end)
