Numerical Control Technology Terms (2)
Acceleration: Acceleration is the measure of increase in velocity of a machine or figurative device over a period of time.
Backlash: Backlash is the clearance between meshing gears or other components to allow for lagging of one component when pressure is applied to the other component. It is measured in degrees.
Coordinate System: Coordinate system is a system of location used to identify the exact position of a point in space by referencing that point to a known point at a specific distance which is defined by x, y, and z coordinates.
Coupling: Coupling is a device capable of connecting two rotating members and allowing the transmission of power between them.
Digital Signal Processing (DSP): Digital Signal Processing (DSP) is the analysis, simulation and manipulation of discrete-time signals and systems.
Feedback Control Systems: Feedback Control Systems are systems consisting of sensors, actuators and control algorithms that are used to automatically control a physical system.
Function Keys: Function Keys are special keys on a computer keyboard used to initiate specific system functions.
G Codes: G Codes are the standard programming language for numerical control (NC) machines and are integral for creating NC programs.
Incremental Motion Control: Incremental Motion Control is an NC system used to position an axis a specific distance from its current position in the NC direction.
Joint Motion Control: Joint motion control is a type of NC system used to move a jointed robotic arm to a given position.
Lead Screw: Lead screw is a threaded rod that is used to transfer forces from a power source, usually a motor, to move a component in a straight line.
Machine Tool Controller: Machine tool controller is a type of NC system that is used to control the movement and operation of a machine.
Programmable Logic Controller (PLC): Programmable Logic Controller (PLC) is an industrial computer controller that is used to interpret and execute instructions in an automated system.
Servo Motor: Servo motor is an electric motor that is used to control the position, speed and/or torque of a machine or component.
Spindle: Spindle is the part of a machine that holds, rotates and drives the work material being machined.
Tool Path Verification: Tool Path Verification is the process of verifying that the tool path generated from a CNC program is accurate.
Touch Plate Offset: Touch Plate Offset is a method for setting the tool offset for a CNC machine.
X-Y-Z Table X-Y-Z Table is a type of axis control system used for linear motion.
