In this section there are all the items necessary to begin the course, the training and graphic simulation software, all the images from the book and a series of appendixes which extend and discuss different topics linked to the programming of numeric control machine tools.
The text explains how to use ISO functions to program helical interpolation in a NC mill or lathe. In addition, the appendix explains how to make a thread using a thread mill tool.
The text explains how to transfer values from the main program to a subprogram, using EXTERN and PROC functions. The setting of a macroinstruction is useful for creating customized work cycles.
Practical on the computer, tablet or smartphone, it contains the major files for the realization of metric ISO threads, cylindrical GAS, conical GAS, NPT, UNC, UNF, UNEF. In addition, it contains distribution tabs of the cutting depths for the manual programming of threads and the drilled holes diameters of tapping.
The text describes the peripheral and frontal milling, analyzing the technological differences, which emerge during the cutting advancement, in accordance or discordance compared to the peripheral speed of the mill. The last chapter contains the calculation method of the working time for the execution of a cut.
The coding of ASCII (American Standard Code for Information Interchange) codes dates back to 1968. ALT+code combination is useful when inserting many of the special characters we frequently use, such as Ø (ALT+157) or × (ALT+158), α (ALT+945).
