401f Integrated CNC Flashcards
(20 cards)
Modern CNC is _____ compared to older generations
More intuitive
What two code types do CNCs read?
G-codes and M-codes
An axis is?
A specific direction of movement
Direction of movement along the X axis
Left to right
Direction of movement along the Y axis?
Depth - front to back
Direction of movement along the Z axis?
Up and down
Direction of movement along the C axis?
Rotational
Position often found in the lower left hand corner of the CNC table
Machine reference zero
The difference between machine reference zero and part reference zero?
MRZ is the zero point of the entire table, PRZ is the zero point of the piece being machined, reguardless of its position on the table
Prepared functions that describe the specific movement of the tool being used by the CNC, programmed by widely used international standards
G-codes
Commands that activate or end the performance of the task being performed by the CNC, that vary between manufacturers
M-codes
What kind of software generates codes from a drawing
CAM
Program for rendering parts
CAD
Is V-Carve considered a CAM or CAD?
CAM, but is kind of both
Where does a CNC store parameters of its tools?
Tool database
The parameter we were told is important to enter?
The length of tool projection from the spindle
In the tool database, G1 refers to
Radius
In the tool database G3 refers to
Cutting length
If your machine is equipped with stop pins, they are merely a guideline to placement
Nope, put that sucker tight against them, they are not just for show
An universal truth about CNC machinery they tried to hide on the last page
They all use a computer to direct the tooling (hence COMPUTER numeric control) and have way better speed, accuracy, repeatability, and productivity compared to other machinery and people, AI is coming for us babes
