90° LEAD MSR E64 Q-2 A-2 Q-3 A-3 Q-4 A-4 Q-5 A-5 Q-6 A-6 What cutting conditions are recommended in most cases for MSR Vc= 500sfm, fz = 0.008ipt, larger cutting depth and smaller cutting width What is the required equipment for MSR 1 In case of MSR100R-2 e.g.) Load Meter 120% e.g.) Load Meter 90% 11 i 1st Pass D.O.C. X ae: 0.59x2.95" A 3rd Pass 2nd Pass D.O.C x ae: 1.77x0.98" Maximum spindle revolution should be lower than 4000RPM. BT50 or larger. The reason it is not recommended for high RPM spindle machines is due to their lower torque value. Although MSR works with BT40 shank, maximum available fz is about 0.004ipt. What are the points to remember when using a lower horsepower machine Do not use large size cutters. 02.5" or 03.0" are recommended Increase cutting speed and decrease feed rate. Set up conditions to get the largest available torque by checking torque curve of the machine. In conditions of Vc = 500sfm, insufficient torque was amiable due to being in high gear. In this case, use Vc which can exert enough torque, such as Vc = 400sfm. Machine torque curve is a priority. How do I deal with an unstable workpiece Decrease feed rate during the initial cut. What tool life can I expect Vibration and workpiece movement are most likely to occur upon the cutters initial entry entry into the cut. Effective combinations for maintaining cycle time while reducing the feedrate. Vc=500sfm, fz=0.008ipt i Vc=650sfm, fz=0.006ipt Example: Chip Weight: 1543lbs/Corner (Result by PR660) Cutting Time: 90min. (Calculated Value) Cutting Distance: 213.25ft (Calculated Value) Metal Removal Rate About 17.20lbs Chips Removed per Minute Tool Life Time = 1543lbs (Chip Weight) 17.20lbs (Chip Evacuation Amount per 1min) = 90min Cutting Distance = 90min (Time by the End of Tool Life) x 28.228ipm (Table Feed Ratio per 1min) = 213.25ft Cutting Vc = 490sfm, D.O.C. x ae: 0.787" x 2.756", Vf = 28.228ipm. Tool: MSR100R-2 (6 Flutes) How do I reduce chattering If chattering occurs, then the following conditions are recommended. Reduce cutting speed and increase feed rate. In case of Steel Vc=250sfm fz=0.010ipt In case of Cast Iron Vc=250sfm fz=0.014ipt 1st Pass 2nd Pass 3rd Pass 8°°.
