here is I think a nice description of what you have to face when cutting a NPT tapered thread. Using. Notation. H = 0.866025p = height of 60deg. sharp V thread. h = 0.800000p = height of thread on product. p = 1/n = pitch (measured parallel to axis) n = number of threads per inch. a = 30deg. = thread flank angle. • Computerized numerical control (CNC) machines -Perform complex operations faster, more A CNC lathe. CNC turning center. A CNC milling machine. A CNC machining center. The CNC Machine Control Unit • CNC program created & stored in MCU (machine control unit) An operator control panel A CNC lathe holds cutting tools with a tool In CNC turning machines, the G92 cycle is generally used for threading. It can be used for straight threading or taper thread cutting operations, as well as one of the most frequently used CNC Turning cycles. As with other thread and screw cycles, the feedrate cannot be controlled to get the thread out correctly during thread cutting. A very simple and basic cnc lathe program to cut threads on a component. This program uses G33 Threading G-Code to cut threads. Only one cut is programmed here, you can add as many cuts as required according to your situation and material. CNC Arc Programming G02 G03 Example.

ØIn the 1960's, CNC machines became available with timesharing on mainframe computers. True NC machines continued to be built. ØBy the 1970's, specialized computers were being manufactured for CNC controls. CNC - 50 Hour Programming Course The thread mill carries out the following path: - on block N330, the mill is positioned at the correct depth, which depends on how many threads the operator chooses to mill in one turn (Fig.5). - block N340, the mill is placed upon the wall of the hole activating the tool radius compensation (Fig.6-1), DESCRIPTION OF MAIN PROGRAM :-. [note :- all dimension in "mm" and thread is metric angle of thread is 60 degree] Calculation :- Depth of thread = 0.6134 x 1.5. = 0.9201. Our aim is to find value of "crest" and "root" u can consider large or smaller diameter . Here, i consider large diameter 50 mm. Crest = Major diameter -0.9201. = 50 - 0.9201. G76 X18.2 Z-18.0 I-0.1 K900 D100 A60 F1.5; G00 X25.0 Z10.0; This cycle contains a lot of information within the G76 line. The X dimension is the core diameter of the thread, the distance between the bottom of the thread tooth to the centreline multiplied by 2. The Z dimension is the distance to the end of the thre
