Citizen mind-wandering program code! What does 1 mean?

In general, spindle loosening and clamping instructions are used when loading and unloading parts, but for multi-spindle lathes, there are other uses: (1) for two-axis synchronous machining. When machining slender shaft parts, the main shaft and the auxiliary shaft are used to clamp the two ends of the parts respectively, and the parts are in a state of tension by using the retraction force during clamping, and then cutting is carried out, which can prevent the taper caused by the tool and improve the machining quality of the parts surface. (2) For CNC machine tools, slender parts several times longer than the rated stroke can be processed by reasonably setting the loosening and clamping instructions of the main shaft and the auxiliary shaft, pulling and feeding for many times, and processing in sections for many times. 0.6mm and 0.8mm step shafts with a length of 96mm were machined by this method on TONUSDECO2000 machine tool (Z axis stroke 64mm). For example, TONUSDECO2000 machine tool is a numerical control machine tool, which is equipped with an improved PNT2O00 (patented product of Tonus) numerical control system based on FANUC 16 system and has the function of electronic cam. Its programming method is different from ordinary turning and milling, and each step is compiled in each program block diagram according to the process.
