Solution:

As you told that you want to become a cnc programmer, this would lead to you become a production head for any organization for which you must have good knowledge of cnc code i am presenting you some cnc code which will be very useful to achieve your goal. All the best

I just want to explain some G code and M code commonly use in this CNC

G00 = Rapid Positing

G01 Linear interpolation

G02 = Circular Interpolation (CW)

G03 = Circular Interpolation (CCW)

G90 = absolue Mode

G90 = Incremental Mode

G95 = Inch per revolution

G21 = Metric unit

G20 = Inch unit

G17 = XY Plane

G18 = ZX Plane

G19 = ZY Plane

M02 = End of program

M03 = Spindle rotation

M04 = Spindle rotation (CCW)

M05 = Spindle stop

M06 Tool Change

M07 = coolant on

M09 = coolant off

Program for Given Drawing:

N01 G90 G20 G94 (Absolute Mode select, Inch system and Revolution per min)

N02 M06 T01 (Tool Change T01 )

N03 G03 S800 (Spindle on clockwise with 800 RPM)

N04 G00 X0 Y0 Z20 (Presetting the tool at origin with height = 20)

N05 G01 Z-75 (Linear interpolation)

N06 G01 X10

N07 G01 Y5

N08 G01 X3

N09 G01 Y3

N10 G01 X0 Y2

There are several models derived from first principles to describe gas diffusion under ideal conditions and all of them utilize very specific assumptions How do the values from both models calculated in part a, compare to the general gas-gas diffusion value of a generic gas molecule diffusing in a gas (the one value given in class)? How do the values from both models calculated in part a, compare to the Einstein-Boltzman general equation for diffusivity of an ideal gas molecule?
