Finite element methods along with the obtained force are then applied to simulate the static force distribution for a circular saw blade. (9) P=R-R2-L22(9). Direct experimental techniques used to study cutting processes are usually costly and time consuming. The optimization process can thus be represented by Equation (22). Since it was custom made, this research aims at obtaining a comprehensive description of the manufacturing process with respect to interacting performance parameters.

Special thanks is hereby extended to Mr Michael Leitch (PEng) for his invaluable contributions during the entire course of the research. of torque and a VDI 60 turret. Results from these analyses were later applied to study the chatter frequency during the machining process, and conduct optimization on the geometry of the blade. The slotting machine considered in this study has been designed and built in-house. Cutting force prediction is very important to optimize machining parameters and monitor machining state. Units used in the above table: A p, A e, D, W - mm or Inch; V f - mm/min or inch/min; V c - m/min or feet/min (); F n - mm/rev or Inch/rev; MRR - Metal Removal Rate CM 3 /min or Inch 3 /min Step 2 - Obtaining the materials Specific Cutting Force (KC1.1) Each material has a Specific Cutting Force coefficient that expresses the force in the cutting direction, required to cut a chip . Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. A comparison of these two methods of calculation illustrates the difference. The process is called blanking, in which a machine known as a die exerts a cutting force, which engineers call a "punch," on the plate material to be manufactured. where, fc expressed in Hz, expressed in revolution/second, and K is the integer value (K=0, 1, 2, ). The balance of these forces results in the force equilibrium. The x-axis is along the cutting direction (tangential direction of the outer circle) and the y-axis is the radial direction pointing to the centre of the circular saw blade. Figure 9 shows the highest blade's teeth deformation of 0.019 mm and 0.017 mm for before and after modification, respectively.
