Machining Lab Exam 3 | CNC Machining

What technological advance in the 1960s was responsible for dramatically increasing the use of numerical control technology? - answer--minicomputer Name two advantages of using CNC equipment instead of manual methods. - answer--- Eliminates variation caused by human interaction during the manual machining process - Faster part production rate How many axes of movement does a basic milling center have? - answer--3 Basic CNC milling centers use a method called __ that allows operators to select operations from menus without having to know a programming language. - answer--conversational language When changing tools manually, wait for the machine axes and the __ to come to a complete stop. - answer--spindle What is the purpose of a dry cycle? - answer--A dry cycle can prevent an accidental machine crash In the __ coordinate system, movement is specified in a positive or negative direction along the X, Y, or Z axis. - answer--cartesian The __ coordinate system specifies movement by giving a straight-line distance and travel angle from a tool's current point location. - answer--polar An __ is a transducer that provides electronic feedback about the position of the moving axes to the control in a CNC machine. - answer--encoder
