【Tips for Cutting Processing】 About Tool Deflection and Bending *Materials Available
To suppress tool deflection, it is important to consider "tool selection based on rigidity"! Technical materials that are helpful for training CAM operators are currently available!
To improve the accuracy of NC machining, controlling "tool deflection" is essential. However, issues such as tool engagement occurring at the vertical walls, corners, and recesses of rib grooves (see image) can lead to machining troubles. To achieve direct engraving without causing these problems, there are three important points to consider: 1. During roughing of rib groove shapes, keep the deflection of the cutting edge below the finishing allowance. 2. To reduce the deflection of the cutting edge, minimize the cutting resistance acting on it. 3. Increase tool rigidity within permissible limits concerning the height of the machining shape and the slope angle of the vertical walls. Therefore, to perform stable cutting operations with small-diameter tools of Φ4 or less, selecting "sturdy" tools, such as pencil neck tools, becomes particularly important.
