The method by which contouring machine tools move from one programmed point to the next is called interpolation. This ability to merge individual axis points into a predefined tool path is built into most of today’s MCUs.

Indexable lathe tool holder with insert, ideal for turning. Suitable for our range of lathe tools.

Curves can be produced with linear interpolation by breaking them into short, straight-line segments. This method has limitations, because a very large number of points would have to be programmed to describe the curve in order to produce a contour shape. A contour programmed in linear interpolation requires the coordinate positions (XY positions in two-axis work) for the start and finish of each line segment. Therefore, the end point of one line or segment becomes the start point for the next segment, and so on, throughout the entire program.

Select four words you think go together and press Submit. If you make a guess and you’re incorrect, you’ll lose a life. If you’re close to having a correct group, you might see a message telling you that you’re one word away from getting it right, but you’ll still need to figure out which one to swap.

Linear Interpolation consists of any programmed points linked together by straight lines, whether the points are close together or far apart

In Connections, you’re presented with a grid of 16 words. Your task is to arrange them into four groups of four by figuring out the links between them. The groups could be things like horror movie franchises, a type of verb or rappers.

2017519 — Work hardening, also known as strain hardening or cold working, is the strengthening of a metal by plastic deformation.

The development of MCUs capable of circular interpolation has greatly simplified the process of programming arcs and circles. To program an arc, the MCU requires only the coordinate positions (the XY axes) of the circle center, the radius of the circle, the start point and end point of the arc being cut, and the direction in which the arc is to be cut (clockwise or counterclockwise)

Each group is color coded. The yellow group is usually the easiest to figure out, blue and green fall in the middle, and the purple group is typically the hardest one to deduce. The purple group often involves wordplay, so bear that in mind.

BALM and GLOSS gave me an entry way into the greens. I wasn’t sure if STAIN belonged there, but I lucked out. I got the yellows next, then ran into a spot of bother.

It took a couple of random guesses that left me “one away” before I figured out the purple group thanks to ANGLE and TEMPERATURE. That left the blues, which I didn’t figure out because CORNER didn’t seem to quite belong there.

M or miscellaneous codes are used to either turn ON or OFF different functions which control certain machine tool operations.

All contouring controls provide linear interpolation, and most controls are capable of both linear and circular interpolation. Helical, parabolic, and cubic interpolation are used by industries that manufacture parts which have complex shapes, such as aerospace parts and dies for car bodies.

G-codes are sometimes called cycle codes because they refer to some action occurring on the X, Y, and/or Z axis of a machine tool.
