Basic Study on Cutting Forces in Gear Cutting : Theory of Cutting with Two Continuous Symmetrical Cutting Edges

Investigation of Cutting Forces Superalloy Inconel 718

Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...

Experimental Study of the Effect of Laser-Cutting Process Parameters on Heat Distribution and Cutting Edge Quality of Steel Sheets

This study aimed to evaluate Laser-cutting process of Mild Steel St37 sheets with two different thicknesses. In order to evaluate the quality of cutting edge and the depth of the area affected by the heat, several tests were conducted to determine the effect of parameters such as Laser power, Laser beam movement speed and pressure of axillary gas on the quality of cutting edge and the depth of ...

Laser Cutting Theory

A laser can be used for cutting by exposing material to the intense heat energy developed by its beam. If that heat input to the material is greater than that material's ability to reflect, conduct, or disperse the added energy, it will cause a sudden rise in temperature of the material at that point. If the temperature rise is substantial enough, the input heat is capable of initialising a hol...

Two-Person Pie-Cutting

Cutting two graphs simultaneously

Consider two graphs, G1 and G2, on the same vertex set V , with |V | = n and Gi having mi edges for i = 1, 2. We give a simple algorithm that partitions V into sets A and B such that eG1(A,B) ≥ m1/2 and eG2(A,B) ≥ m2/2−∆(G2)/2. We also show, using a probabilistic method, that if G1 and G2 belong to certain classes of graphs, (for instance, if G1 and G2 both have a density of at least 2/3, or if...
