What does CNC stand for?
CNC: Computer Numerical Control - A system for automating machine tools through software-driven commands to precisely control machining operations.
What is a Mill?
A machine tool used for removing material by advancing a cutter into a workpiece, creating flat, curved, or complex shapes.
What is G-Code?
A standardized programming language used in CNC to control the movement and operations of machine tools.
What is M-Code?
Machine-specific codes in CNC programming used for auxiliary functions like turning coolant on or off.
What is a Toolpath?
The programmed trajectory that a cutting tool follows during machining to achieve the desired geometry.
What is a Spindle?
The rotating axis in a CNC machine that holds and drives the cutting tool or workpiece.
What is an End Mill?
A versatile cutting tool with cutting edges on the sides and tip, commonly used in milling operations.
What is Face Milling?
A machining process that uses the face of a cutting tool to create a flat surface.
What is Profile Milling?
A process for cutting the outline or shape of a part, either externally or internally.
What is a Workpiece?
The raw material that is machined into a desired shape or finished product.
What is Fixturing?
The method or device used to secure a workpiece during machining to ensure accuracy and stability.
What does CAD stand for?
CAD: Computer-Aided Design - Software for creating 2D and 3D part designs for manufacturing.
What does CAM stand for?
CAM: Computer-Aided Manufacturing - Software that converts CAD models into machine instructions for CNC machines.
What is Feed Rate?
The speed at which the cutting tool or workpiece moves during machining, typically measured in inches per minute (IPM).
What does RPM stand for?
RPM: Revolutions Per Minute - The rotational speed of the spindle or cutting tool.
What is Chip Load?
The thickness of material removed by a cutting tool per cutting edge in one revolution.
What is Tapping?
The process of creating internal threads in a pre-drilled hole for screws or bolts.
What is Peck Drilling?
A drilling method where the tool is retracted periodically to remove chips and reduce heat.
What is Coolant?
A fluid used to reduce heat and friction during machining, improving tool life and surface finish.
What is an Axis in CNC?
A direction of movement in CNC machines, typically X, Y, and Z for linear motion, and A, B, and C for rotational.
What is 5-Axis Machining?
CNC machining with motion along three linear axes and two rotational axes, enabling complex parts.
What is Tolerance?
The allowable variation from specified dimensions in a machined part.
What is a Datum?
A reference point or surface used for measurements and machine setup.
What is Backlash?
The loss of motion or play between mechanical components in a CNC machine, affecting accuracy.
