What is a CNC plasma cutter?

A CNC plasma cutter is a type of CNC machine that uses a plasma torch to cut metal and other materials. The plasma torch is guided along a programmed path to produce the desired shape.

What is CNC Haas?

Haas is a brand of CNC machine tools, including CNC lathes, mills, and routers. Haas CNC machines are known for their reliability and ease of use.

What is a CNC controller?

A CNC controller is the brain of a CNC machine, it interprets the G-Code and controls the movement of the machine to produce the desired outcome.

What is a CNC machine cycle?

A CNC machine cycle is the series of steps that a CNC machine performs to complete a task, such as cutting, drilling, or shaping a workpiece.

What is CNC turning?

CNC turning is the process of using a CNC lathe to turn a workpiece, such as a metal rod, to produce a cylindrical shape.

What is CNC milling?

CNC milling is the process of using a CNC mill to cut, shape, and drill a workpiece, such as a metal block, to produce a specific shape or design.


What is a CNC simulation?

A CNC simulation is a virtual representation of a CNC machine and its process, used to verify the accuracy and feasibility of a CNC program before it is executed on a physical machine.

What is a CNC retrofit?

A CNC retrofit is the process of upgrading an existing manual machine, such as a lathe or mill, with computer numerical control technology.

What is CNC precision?

CNC precision refers to the accuracy and consistency of a CNC machine’s movements, which directly affects the quality and consistency of the final product.

What is CNC tolerance?

CNC tolerance is the acceptable deviation from the intended dimensions or position of a workpiece, as specified by the CNC program or design specifications.

What is a CNC fixture?

A CNC fixture is a device used to secure and position a workpiece in a CNC machine, ensuring that the workpiece is properly aligned for the desired machining process.

What is a CNC spindle?

A CNC spindle is the rotating part of a CNC machine, such as a lathe or mill, that holds and drives the cutting tool.

What is a CNC chuck?

A CNC chuck is a device used to secure and rotate a workpiece in a CNC machine, usually in a CNC lathe.

What is CNC probing?

CNC probing is the process of using a touch probe or other device to accurately measure the position and orientation of a workpiece in a CNC machine, for the purpose of determining the starting point for a machining process.


What is a CNC workholding device?

A CNC workholding device is a device used to secure and position a workpiece in a CNC machine, ensuring that the workpiece is properly aligned for the desired machining process. Examples include vises, clamps, and fixtures.

What is a CNC cutting tool?

A CNC cutting tool is a tool used to cut and shape material in a CNC machine, such as a lathe or mill. Examples include drill bits, end mills, and turning tools.

What is CNC tool offset?

CNC tool offset is the difference between the actual position of a cutting tool and its programmed position. This offset can be used to compensate for tool wear and other factors that can affect tool accuracy.

What is CNC tool life?

CNC tool life is the amount of time a cutting tool can be used before it needs to be replaced, as determined by factors such as tool wear, material hardness, and cutting speed.

What is CNC machine maintenance?

CNC machine maintenance is the process of regularly inspecting, cleaning, and repairing a CNC machine to ensure its continued proper operation.

What is CNC machine downtime?

CNC machine downtime is the period of time during which a CNC machine is not in operation, either due to scheduled maintenance, repairs, or unexpected failures.

What is a CNC operator?

A CNC operator is a person responsible for operating a CNC machine, setting up the machine and workpieces, monitoring the machining process, and making any necessary adjustments to ensure the desired outcome.


What is G-code in CNC programming?

G-code is a standardized programming language used in CNC programming to control the movements and actions of a CNC machine. It consists of a series of letters and numbers that instruct the machine on specific actions to perform, such as moving, cutting, and drilling.

What is M-code in CNC programming?

M-code, or miscellaneous code, is a type of G-code used in CNC programming to control non-movement-related functions of a CNC machine, such as turning on and off coolant, activating tool changers, and starting and stopping spindles.

What is a CNC program file?

A CNC program file is a digital file that contains the G-code and M-code instructions used to control a CNC machine. The file is loaded into the CNC controller and executed to produce the desired outcome.

What is a CNC subroutine?

A CNC subroutine is a block of code that can be reused in a CNC program, allowing for more efficient and modular programming. Subroutines can be called multiple times within a program, reducing the amount of code that needs to be written and making it easier to make changes to the program.

What is CNC error compensation?

CNC error compensation is the process of adjusting for errors and inaccuracies in a CNC machine’s movements, such as tool wear or misalignment, to ensure the desired outcome.

What is CNC machine tool calibration?

CNC machine tool calibration is the process of adjusting and verifying the accuracy of a CNC machine’s movements and measurements, using precision measuring instruments and software.

What is CNC machine tool path verification?

CNC machine tool path verification is the process of checking the accuracy and feasibility of a CNC program’s tool path, either by simulating the machining process or by running a small section of the program on the CNC machine.
