Toolholding & Workholding
Big Ideas for Workholding
Holding large workpieces, especially heavy ones, requires parts manufacturers be more mindful of workholder and machine tool limits than they have to be with smaller workpieces. Also, shops may need to improvise when a conventional workholder can't secure a large workpiece.
Kicking Out Bad Vibration
High-speed, vibration-free endmilling of aluminum workpieces requires cutting tools with certain features and requires certain types of toolholders. Also, it can be aided by cutting strategies.
Chuck Checkout
Gripping power, friction and hysteresis are important factors in selecting a 3-jaw chuck to maximize a CNC lathe's accuracy and horsepower.
