Answer 1

Explanation:

Part programming for CNC machine

Part programming is a program done for the production of a component by using standard codes known as the part program.
Code is nothing but the name of a program written for producing standard movement of the tool.

G-codes: These are the general-purpose codes. Some of the G codes with their purpose are:

G-Code	Function
G-00	Rapid transverse
G-01	Linear interpolation
G-02	Circular interpolation (CW)
G-03	Circular interpolation (CCW)
G-04	Dwell
G-05	Hold/Delay
G-06	Parabolic Interpolation
G-08	Acceleration of feed rate
G-09	Deceleration of feed rate
G-17	XY Plane designation
G-18	ZX Plane designation
G-19	YZ Plane designation
G-20	English units of input
G-21	Metric units of input
G-35	Thread cutting, linearly decreasing lead
G-40	Cutter compensation cancels to zero
G-41	Cutter radius compensation - offset left
G-42	Cutter radius compensation - offset right
G-43	Cutter compensation positive
G-44	Cutter compensation negative
G-63	Tapping cycle
G-64	Change in feed rate or speed
G-70	Dimensioning in inch units
G-71	Dimensioning in metric units
G-80	Canned cycle cancelled
G-81	Canned drilling cycle
G-89	Canned boring cycle
G-90	Absolute input dimensions
G-91	Incremental input dimensions
G-97	Spindle speed in revolution per minute

Important Point

M-codes: These are the miscellaneous codes that tell a machine how to act.

Some of the M-codes with their purpose are:

M-Code	Purpose
M00	Program stop
M01	Optional program stop
M02	Program end
M03	Spindle ON clockwise
M04	Spindle ON counterclockwise
M05	Spindle OFF
M06	Tool change
M08	Coolant ON
M09	Coolant OFF
M10	Chuck or rotary table clamp ON
M11	Chuck or rotary table clamp OFF
M30	Program end, return to start
