Definition of cnc

(Computerized Numerical Control) This is a special appliance used by many cue manufacturers to design the inlays on a cue to precision accuracy. Often times it is looked down upon because this technology departs from the previous standard of "handcrafting" inlays, using a pantograph tool. However, the new technology allows for much more precise cuts at a quicker pace. If you are looking to save some money and appreciate the man made designs that are computer inlayed in your cue, then CNC is the technology for you.

24 Random Essential Billiards Terms

Deviation of a ball from its initial direction of travel. Often the result of a poor-quality table and may be an artifact of the cloth, the bed, a ball with uneven weight distribution, or simply the floor the table stands on being uneven.
The 'Lady Jane Grey' is a rarely used term to describe a shot in the game of snooker. The cue ball is baulk side of the spotted black after potting a red ball. The black is powerfully potted into a top corner pocket and the cue ball bounces off the top cushion into the red balls, moving them into space, thus allowing the continuation of a break. Named after Lady Jane Grey, the 16th Century Queen of England, possibly because the speed the cue ball must be hit matches the speed with which she was deposed from the throne.
Also spot-stroke, spot hazard. A form of nurse shot in English billiards, in which the red ball, which must be spotted to a specific location after every time it is potted before another shot is taken, is potted in such as way as to leave the cue ball in position to repeat the same shot, permitting a skilled player to rack up many points in a single break (series of shots in one visit).
Sandbagging, in any handicapped sport, is the unethical practice of deliberately playing below your ability in order to alter your handicap so it does not reflect your true ability.
A tactic employed in UK eight-ball pool in which a player calls and pots one of the balls in a favorably lying set, then plays safe, leaving as many of his/her well-placed balls on the table as possible, until the opponents commits a foul or leaves a chance that the player feels warrants an attempt at running out.
More commonly known as "straight pool", it was for many years the most popular game in pool and the game on which all World Championships were based.
14.1 is a call-shot game played with all 15 numbered balls and cue ball. Every ball pocketed counts as one point and a game is played to a agreed up score, generally 50, 100, or 150 points.
Traditional straight pool matches are played to 150 points.14.1 is also called "continuous pool" because, after the opening break, play continues until a player reaches the winning score. When only one numbered ball is left on the table, the remaining 14 are racked (with the apex ball missing), and play continues.
A geometric form, usually aluminum, wooden or plastic, used to assist in setting up balls in games like eight-ball, nine-ball, and snooker. The rack allows for more consistently tight grouping of balls, which is necessary for a successful break shot. In most games a triangle-shaped rack capable of holding fifteen balls can be employed, even if the game calls for racking less than a full ball set, such as in the game of nine-ball. For further information, see the Rack (billiards) main article.
In some games, refers to a single frame.
Technique using different wood inlays to create picture designs on the butt of the cue.
This is playing to a higher winning score than eight in the game of one pocket.
Also yellow(s).
In snooker, the lowest-value colour ball on the table, being worth two points. It is one of the baulk colours.
In blackball, one of two groups of seven object balls that must be potted before the eight ball; compare stripes; contrast red ball.
This is an imaginary line that separates the halves of the table by crossing at the middle of the side of pockets.
This is when you aim at one particular object ball that is not meant to go in the pocket, but is instead meant to contact another object ball which will continue the combination process or be pocketed.
Also topspin, top-spin, top. Same as follow. Contrast bottom spin, back spin.
This is the white ball in carom games which is separated from the clear ball by a marking (usually a dot or spot).
This term refers to a low percentage one pocket shot.
This is a location where a player can go inexpensively to refine their pool skills. These establishments began as horserace betting houses, and are still often filled with games involving money action. If you get thirsty, many pool halls offer cold refreshments, however, be careful you are not there just for the refreshments. In that case, you may as well be playing at a bar with a bent cue on a rain table.
In blackball, a situation where the player cannot see any of the balls she/he wants to hit due to obstruction by other balls or the knuckle of a pocket. The player must call "total snooker" to the referee, which allows a dispensation to the player from having to hit a cushion after contacting the object ball, which is otherwise a foul.
A shot aimed so that the center of the cue ball is in line with the edge of the object ball, eclipsing half of the ball. "Hit it just a little thinner than half-ball." Assuming a cling does not occur, the shot will impart post-contact momentum on the object ball in a direction 30° (which is arcsin(1 - x), where x is the fraction of object ball eclipsed: ½ in this case) off the direction of the cue-ball's pre-contact momentum. Also notable because the carom angle the cue ball takes is more consistent than at other contact points.
Also goose neck rest. Same as swan.
To fail to make a legal shot.
A joint type in which the butt and shaft screw together in a tight lock, resulting in a better shot with more hitting power.
Also simply maximum. In snooker, the highest break attainable with the balls that are racked; usually 147 points starting by potting fifteen reds, in combination with blacks, and clearing the colours. Also called a 147 (one-four-seven). In six-red snooker, the maximum break is only 75 points, due to fewer red balls and thus fewer black-scoring opportunities.
This refers to the cluster of balls remaining in a similar position to where they were within the break.
Same as gutter table. A table with a ball return system, as opposed to a drop pocket table.
