unit 5 Coordinates & axis and motion

Remembering: What is a coordinate system in CNC Programming?

• A set of points that describe a location in space
• A method of measuring the length of a part
• A system of measuring the speed of a machine tool
• A system of measuring the temperature of a machine tool

Remembering: What are the types of coordinate systems used in CNC programming?

• Absolute and Incremental
• Positive and Negative
• Left and Right
• Up and Down

Understanding: What is the difference between an absolute and incremental coordinate system?

• Absolute coordinate system uses a fixed zero point while incremental uses a moving zero point
• Absolute coordinate system uses a moving zero point while incremental uses a fixed zero point
• Absolute coordinate system uses a positive point while incremental uses a negative point
• Absolute coordinate system uses a negative point while incremental uses a positive point

Analyzing: How does the choice of coordinate system affect CNC programming?

• It has no effect on programming
• It affects the accuracy of the programming
• It affects the speed of the programming
• It affects the complexity of the programming

Evaluating: Which coordinate system is preferred for complex CNC programming?

• Absolute
• Incremental
• Either one can be used for complex programming
• It depends on the type of machine tool being used

Remembering: What is the definition of axis in CNC machining?

• A line about which a body rotates
• A tool used to cut material
• A unit of measurement in CNC machining
• The direction in which a tool moves

Remembering: What is the definition of motion in CNC machining?

• The movement of a tool along a path
• The speed of a tool during cutting
• The direction in which a tool moves
• The measurement of the angle of a tool

Understanding: What are the three types of motion in CNC machining?

• Linear, rotary, and angular
• Forward, backward, and stationary
• Up, down, and diagonal
• Right, left, and center

Applying: How is linear motion in CNC machining achieved?

• By moving the tool along a straight line
• By rotating the tool around a center point
• By changing the angle of the tool
• By moving the tool in a circular path

Evaluating: What type of motion is necessary to make circular cuts in CNC machining?

• Linear
• Rotary
• Angular
• Stationary
