CNC Machining Types and Terms
Types of CNC Machining
- is an
automatic machine process utilizing a drill to cut parts.
- is
a place where materials are shaped by CNC machines.
- ,
also known as "CNC turning," is possibly the most common kind
of CNC machining. CNC milling machines are classified according to the
number of axis points that they use. Typically these machines have at
least three axes, X and Y for horizontal movements, and Z for verticals;
some machines, however, utilize five axis points with extra pivot points.
- cut
parts on computer numeric control systems.
- shapes
materials into precise forms.
- is the precision cutting of parts with a laser using CNC machines
to control the laser to ensure accuracy.
- is the process that uses a computerized machine to ensure exactitude.
- is
often performed by CNC machines to create a part or object which will
be a "mock-up" or model of a future final part. Prototypes
are used to prove feasibility, but often are not as efficient or well-designed
as later production models.
CNC Machining Terms
- A
machine tool members circular axis motion or slide about the x-axis; values
along the a-axis are the degrees of rotation about the x-axis.
- An NC system
that ensures all positional dimensions are in reference to a shared
datum point; includes both feedback and input.
- Referring to a system
which utilizes electrical voltage ratios or magnitudes to represent physical
axis positions.
- Established by the American Standards Association
as a data transmission code in America.
- The relative movements
of a work piece or tool in a primary direction, consisting of
three linear axes, which are at ninety degree angles from each other;
the X,Y for horizontal movement and Z for vertical movement.
- A characteristic
of a numerically controlled unit that gives operators the ability to
withhold command information from machine tool slides.
- Also called "mirror image," this
machining command procedure is used to create a reverse or mirrored part
by reversing the plus and minus values along a given axis; mirror imaging
makes a left oriented part using a right handed oriented tool path; circular
interpolation also reverses.
-
A CNC controller language using the EIA/ANSI 494 software.
- The relative movement
between interacting mechanical parts as a result of looseness.
- Circular motion of
a machine tool along around the y-axis.
- Code based on
binary numbers expressed as either 1 or 0, denoting true/false or on/off,
etc. The primary programming language of CNC machines.
- A single line of NC
code representing enough information to a CNC machine to execute a single
arc or line movement.
- A function allowing
the control system to ignore any select block of code, at the operators
control.
- Computer Aided Design /
Computer Aided Manufacturing; this is the use of computers to assist in
both the development and manufacturing phases.
-
Utilizing computers to assist the development phase of design.
- Utilizing computers to assist in manufacturing processes by the
computerized control of the tooling process.
- Coordination
between two axes produces an arc and its curvature is clockwise in respect
to the part being machined and the Cartesian planes.
- Coordination
between two axes produces an arc that has a curvature that is counterclockwise
in respect to the part being machined and the Cartesian planes.
- The assembly language
for CNC devices. Each machine instruction corresponds to a fundamental
movement of the robotic mechanism.
- A thin fin of material
which forms at the parting line of the mold.
- A machine tool for shaping
metal or other material. The material is turned about a horizontal axis
while it is shaped by a fixed tool.
- A control
function in which data points are created between given coordinate positions
to permit simultaneous movement along one or more axes of motion in a
linear path.
- The
process of creating a manuscript in the machine control language format
that defines the series of commands for a CNC machine.
- The retention of information
by a CNC computer system until new information is received to replace
it.
- A displacement of a
tool along an axial direction the same as the difference between the real
length and the inputted tool length.
- The quantity to
which axis motion goes beyond the targeted value.
- The variables which
determine the dimensions of a machined part as well as the operational
sequence of the machine tools used to produce the part.
- The selection of tools
needed to produce the desired contours and dimensions of a machined metal
part.
