If a square shoulder milling cutter is used for rough milling of the cavity

If you use a square shoulder milling cutter (with a triangular insert) with a weaker nose, it will produce unpredictable cutting effects. At the maximum cutting depth, the entering angle is 45 degrees.

This article comes from China Hotspot Mould Net. If it is used, the transition between adjacent tool paths is smoother, and it can also leave a smaller and more uniform processing for semi-finishing. When cutting along a straight wall with an outer circle, the entering angle is 90 degrees. Triangular or diamond-shaped inserts will also produce greater radial cutting force, and because the number of cutting edges of the insert <a href="https://www.info-plastic.com/product/kitchen-storage/8513big-hollow-out-receiving-basket.html">kitchen hollow out receiving basket</a> is small, they are economical roughing tools. This allows them to use higher feed rates than most other blades. The result is to leave uneven machining allowance for finishing, thereby affecting the geometric accuracy of the mold. This also explains why the strength of the round blade tool is large-the cutting load is gradually increasing. The entering angle of the round insert is changed from almost zero (very shallow cutting) to 90 degrees, and the cutting action is very smooth.What is the most common use of round insert milling cutters as the first choice for mold roughing tools?

If a square shoulder milling cutter is used for rough milling of the cavity, a large amount of stepped cutting allowance must be removed in the semi-finishing process. Roughing and semi-roughing should always use round blade milling cutters, such as CoroMill200 (see mold making catalog C-1102:1) as the first choice.. margin. In 5-axis cutting, the round insert is very suitable, especially since it has no restrictions. On the other hand, the round insert can be milled in various materials and in all directions. By using good programming, round blade milling cutters can largely replace ball end mills. The round blade with small runout is combined with the finely ground, positive rake angle and light cutting geometry, and can also be used for semi-finishing and some finishing processes. One of the characteristics of round blades is that the thickness of the chips they produce is variable. This will change the cutting force and bend the tool
