The ____ axis normally describes the longer direction of travel on the machine, and the ____ axis describes the shorter direction of travel. - ANSWER-X-axis, Y-axis Each CNC machine has a built-in location that is called ____. This point is typically located at the _____ direction along the X-, Y-, and Z-axes, and cannot be changed by anyone after it leaves the original manufacturer. - ANSWER-machine zero, farthest positive In addition to machine zero, each part program sets a starting location called ____. - ANSWER-program zero If the G codes tell the machine "what to do," and the X, Y, and Z codes tell the machine "where to do it," the ___ and ___ codes tell the machine "how fast to do it." These codes are used to set the feed and speed for the machine as it performs a cutting operation. - ANSWER-F, S ___ codes tell the computer to choose a specific tool, and ____ codes might tell the computer an assortment of miscellaneous commands. - ANSWER-T, M The ____ is the series of movements made by a single cutting tool. - ANSWER-toolpath Before the operator runs a program for the first time, he or she must set program zero. You may also see this position referred to as ___ or ___ zero. - ANSWER-work zero or part On a lathe, ___ offsets adjust the entire turret along the Z-axis from home position. This offset affects every tool in the turret. - ANSWER-Workshift On a lathe, ___ offsets adjust cutting tools along both the X-axis and Z-axis. This offset affects only one cutting tool. - ANSWER-Geometry The ___ sets the starting place for all the other geometry offsets of other tools - ANSWER-reference tool Cutting forces, part deflection, tool wear, etc. can potentially cause slight changes to tool location and variations in measurements. ___ offsets act as the minor adjustments that compensate for these variables. - ANSWER-Wear On a mill, ___ offsets compensate for varying tool lengths in the Z-axis. Each tool has its own offset. - ANSWER-Tool length On a mill, ___ adjusts for varying tool diameters. It is only necessary for tools that travel in the X- and Y-axes. - ANSWER-Cutter radius compensation (CRC) Like the turning offsets, a workshift offset affects the position of every tool held in the mac
