Absolute coordinate values are based on the origin (0,0,0). To enter an absolute X, Y, Z coordinate, specify a point by entering its X and Y values in the format X, Y, Z. Use absolute X, Y, Z coordinates when you know the precise X and Z and Y and Z values of the location of the point. Actuator: A motor or transducer that converts electrical, hydraulic, or pneumatic energy to affect motion. Artificial Intelligence: A machine’s ability through sensors and software to make decisions. Assembly Constraint: Specifies the relative placement or position of two parts or subassemblies and defines a geometric relationship or condition between them. There are four assembly constraints: Mate, flush, angle, and insert. Like part modeling constraints, assembly constraints eliminate degrees of freedom. Automatic Tool Changer: A device that allows for quick tool change in a machine process. Automation: When most or all of the machines/processes run with little or no human control; to perform work without the aid of people. Axis: A line or a linear solid edge, an axis of an arc, a cylinder, cone or torus, a work axis, or two point entities. AMWORKAXIS is the reference line of a coordinate system based on two axes: X and Y. Bottlenecks: A point in a production line where parts back up and are delayed. Brainstorming: When groups of people talk about their ideas. Break-Even Analysis: A report used to calculate the break-even point. CAM: Computer-aided manufacturing; controlling several processes at one time with computers. CIM: Computer-integrated manufacturing. Circular Interpolation: The controlled movement of multiple axes which results in a tool traveling through all the theoretical points along a programmed arc path.

All rights reserved. 8 Closed Loop Control: Control achieved by feedback (i.e., by measuring the degree to which actual system response conforms to desired system response and utilizing the difference to drive the system into conformance). CNC: Computer Numerical Control (acronym); a form of numerical control that uses a dedicated computer as the tool controller. Code: In NC programming, the same word, typically used for G and M words, also a general term for a set of programming instructions. Combining: Process used to add one part to another. Combining Tools: Add one part to another using tools. Compressing: A process that squeezes materials into desired shapes. Contact Sensors: A sensor that identifies when the manipulator on the robot comes in contact with an object. Continuous Manufacturing: Making a large number of one product using mass production. Continuous Path: A method of programming a robot that will move the manipulator through a constant path. Example applications are caulking, gluing, welding and spray painting. Controller: A system of hardware and software that controls the operation of a machine, such as a robot or NC machine tool. For motion control, it may use either nonserve techniques, which control end points only, or a servo control of the path and speed. Controller Box: Computer hardware that houses the electronics to interpret part programs and send them to the CNC machine. Coordinate System: A method by which an assemblage of values is used to define a point in space. Cylindrical Configuration System: A robot design that is based on a robot that will move about a cylindrical axis. Design Analysis: Determines if a product will function as intended. Ethics: Is concerned with standards, rules or guidelines for morally or socially approved conduct such as being honest or trustworthy or acting in the best interest of a society. Ethics addresses questions about morality — that is, concepts such as good and bad, noble and ignoble, right and wrong, justice and virtue. Copyright © Texas Education Agency, 2012. All rights reserved. 9 Handshake: The electrical connection between the computer and the interface; the ability to communicate. Honesty: Honesty refers to a facet of moral character and denotes positive, virtuous attributes such as integrity, truthfulness, and straightforwardness along with the absence of lying, cheating, or theft. Fair and just, free of deceit and untruthfulness, sincere. Integrity: Moral excellence or having a sense of honesty and truthfulness in regard to the motivations for one’s actions. Integrity has to do with consistency of actions, values, methods, measures, principles, expectations and outcomes. Leadership: Is stated as the process of social influence in which one person can enlist the aid and support of others in the accomplishment of a common task. Mill: An abbreviated term for milling machine; a machine tool, usually numerically controlled, capable of automatically drilling, reaming, tapping, milling, and boring multiple faces of a part. Milling Machine: Horizontal or vertical device that uses a cutter to remove material in the X, Y, or Z axis to a precision measurement. Non-Contact Sensor: A sensing device that detects the absence or presence of an object within a certain distance; sometimes called a Proximity Sensor. Operation Process Chart: A chart listing all the processes needed to make a product. Production Engineering: Planning which manufacturing system will be used to make a product. Program: A set of detailed operation instructions for a mechanical or electronic device. Quality Control: A formal program of monitoring product quality by applying statistical process control methods. Rapid Prototyping: In the manufacturing arena, productivity is achieved by guiding a product from concept to market quickly and inexpensively. Rapid prototyping was commercially introduced in 1987 with the development of Stereo Lithography. Rapid prototyping technology automates the fabrication of a prototype part from a threedimensional CAD drawing. This physical model conveys more complete information about the product earlier in the development cycle. The turnaround time for a typical rapid prototype part can take a few days. Conventional prototyping may take weeks or even months, depending on the method used. Other terms applied to rapid prototyping technology include desktop manufacturing, automated fabrication, tool-less manufacturing, or free-form fabrication. Copyright © Texas Education Agency, 2012.
