Automation in Manufacturinghttps://onlinecourses.nptel.ac.in/noc20_me58/previewDr. Shrikrishna N. JoshiMechanical EngineeringIIT GuwahatiLinear interpolation is used for straight-line machining between two points. Circular interpolation is used for circles and arcs. Helical interpolation, used for threads and helical forms, is available on many CNC machines. Parabolic and cubic interpolation are used by industries that manufacture parts having complex shape such as aerospace .Two basic interpolation techniques common to most CNCs are linear and circular interpolation [12,13]. In linear interpolation, the objective is to move the tool from one point to another following .

When using the R value with circular interpolation programming you can tell the machine to do an arc of greater than 180 deg by using a minus value .G01 Linear Interpolation Motion (Group 01) F - Feedrate * X - X-Axis motion command * Y - Y-Axis motion command * Z - Z-Axis motion command * A - A-Axis motion command * B - B-Axis motion command * C - C-axis motion command * ,R - Radius of the arc * ,C - Chamfer distance *indicates optional. G01 moves the axes at a commanded feed rate. It is primarily used to cut . The G01 command is an essential component of G-code that enables linear interpolation. With this command, CNC machines and 3D printers can move in a straight line at a specified feed rate or speed. Linear interpolation involves moving the machine or extruder from the current position to an end position along a straight path.
G00 [Rapid Travel] vs G01 [Linear Interpolation] G01 is a very similar command. It also controls straight line movement, otherwise known as linear interpolation, of the CNC machine. The difference between the two is that G01 will not move at maximum speed and will instead move at the last feed rate listed in the CNC program using the F command.
Traditional CNC only provides linear and arc interpolation, while non-linear and arc curves are interpolated by segmented fitting of linear and arc. This method will lead to a series of problems such as large amount of data, poor accuracy, uneven feed speed and complex programming when processing complex curves, which will inevitably have a .
Rather, Stairs Method should be used in applications seeking maximum feedrate. An improved DSM was suggested for application incorporating large radii, accuracy and smoothness (Koren and Masory, 1981). 5. Linear and Parametric Interpolators The linear-interpolation technique has been widely used in CNC machining because of its simplicity.
Interpolation milling gives the machine the ability to generate linear and radial shapes using the linear axis and a rotary axis creating a straight line into a radial shape so on so forth. Using multiple axises of the machine in this case you have a a live end mill you have a rotary a rotary axis and a linear axis.
For example, N001 G01 X50 Y25 is part of the g code list for programming CNC machines. In this example, N001 represents the line number and G01 X50 Y25 means linear interpolation move to x=50 y=25 coordinate positions, utilizing the reference list for accuracy. – Linear Interpolation (G01): Linear interpolation is smoothly moving multiple axes of the machine so the tool follows a straight line as closely as possible. Since the line is usually not aligned with an exis, this requires motion from more than one axis to “stair step” together to produce this diagonal motion.28 May 1993. Revised: 1 September 1993 the desired trajectories. This process of command generation is usually performed via a device called an 'interpolator' that is located in the controller of the CNC machine. The linear-interpolation technique has been widely used in CNC machining because of its simplicity.Linear interpolation: Machines capable of linear interpolation have a continuous-path control system - meaning that the drive motors on the various axes can operate at varying rates of speed Virtually all modern CNC controls utilize continuous path controls When cutting an angle the MCU calculates the angle based on the programmed coordinates
The term linear interpolation means that the control system is capable to calculate thousands of intermediate coordinate points between the start point and end point of the cut. Result of this calculation is the shortest path between the two points. All calculations are automatic - the control system constantly coordinates and adjusts the feedrate for all cutting axes, normally.

Explanation: Linear interpolation, circular interpolation, helical interpolation, and parabolic & cubic interpolation methods are used for continuous path control in Numerical Control machines. Linear interpolation is used for a straight path.
The sequence of the linear segments approximating the desired path is traced by the system’s linear interpolator on a one-at-a-time basis. Inevitably, their processing induces repeated acceleration–deceleration cycles on the machine and consequently machining inaccuracies are raised with the machining time increasing substantially.
G01 is one of the most basic and common G-code commands in CNC programming. It instructs the machine to move the tool in a straight line at a specified feed rate to a given position. G01 is also known as linear interpolation or linear feed move. Usage Format. The general format of G01 command is: G01 X Y Z F. where: A CNC linear interpolation command should never be used outside the work area because it can cause the machine to move beyond its intended limits, potentially causing damage to the machine or the workpiece. The work area is the designated space where the machine is programmed to operate, and any commands executed outside this area can lead to .G02 instructs the CNC machine to move along a Circular Arc from its current position to a new coordinate. The movement is performed with a controlled federate. The new coordinate can be absolute or relative, depending on the effective mode . .
