![]() Computers may be trained to handle nuances well, but it's questionable how much training may be done within a dataset for accurate patterned autocoding. It may be helpful to think of NVivo as more of a generalist tool without the tailored nuances of pre-set text analysis "thesauruses" and sophisticated stopwords lists. The clearer the coding, the easier it is for machine emulation. ![]() NVivo captures words and their synonyms well. What NVivo captures in the patterned autocoding includes coding of certain disambiguated term-based phenomena, with words that are original or in original order. This latter case of non-consumptive reading is one in which machine algorithms may be used to explore and probe copyrighted textual contents which are not made available for direct human reading.) Machine coding could be used to analyze sentiment…with a training set by human coders to indicate which type of emotions or attitudes fit into which categories (and at what strength or “direction”). This approach does not preclude human "close reading" except in cases when such consumption is not possible. (Franco Moretti of Stanford University coined the term "distant reading." This term refers to the uses of computational methods to consume texts and resultant data visualizations-graphs, maps, networks, trees, and other representations-to represent textual contents. In such cases, "distant reading" by machine counts and machine text summarizations may be desirable. Web-scale contents from social media platforms could be one example of such a large set. There may be contexts in which there are “big data” sets that may not be humanly readable given the volume. After all, most research fields require “close readings” of texts by in-field experts.

I used some macro statements to calculate each angle for the G51 command. ![]() I've used rotation to mill the profile of a large 50-tooth gear by programming one tooth of the gear in a subroutine, then calling the sub 50 times with an angular rotation each time. Some machines like Monarch use a probing routine to check the fixture and compensate with a wee bit of rotation automatically. ![]() Rotation is nice if you have a fixture that's not quite lined up with an axis, and you want to avoid using an indicator it to make it straight. All the points in your program will be rotated around a center point by the angle you specify. If the center point you specify isn't in the center of the pocket, the pocket will be scaled in X like before, but it will also "shift" in the X axis also. For example, if you program your machine to mill a square pocket, you can set the scale center point to the center of the pocket, scale X to say, 90%, and you'll cut a rectangular pocket with the X dimensions shrunk by 10%. It's useful for compensating for a shrinkage factor, or for making non-circular arcs. You can scale one axis at a time, or you can scale multiple axes if you want. The scaling option expands or shrinks all the points around a "center point". According to Dan Fritz explain coordinate rotation & scaling?Īxis scaling (G51, G50) and axis rotation (G68, G69) are options that not very many people use, but they are helpful in some situations. ![]()
