“…Tool wear is a critical topic affecting the economics of machining, especially in connection with the tapping process, since it is one of the last operations to be performed within most operation sequences. 203 It has been reported that the total tapping load consists of the base load and a chip-packing load. The base load results from chip formation and tool/workpiece friction, whereas the chip-packing load is the result of chip clogging in the flutes, and is random in nature.…”

“…Assisted ultrasonic machining has been proven to be an efficient technique for improving the machinability of several aeronautic materials such as aluminum [9,10] or Inconel 718 [11]. Chip breaking, burr generation, workpiece roughness, tool life or torque and cutting forces are some parameters studied with vibration applied in conventional cutting processes [12][13][14].…”

“…7 It was specified that during the tapping of deep holes with small-diameter taps, the reason for frequent tool breakage was the higher torque during threading. 8 The lowest cutting torque in the tapping operations was obtained under dry-cutting conditions. 9 It was stated that the cutting liquids containing fluorine formed a lubricant film layer between the tool and workpiece interface, which led to an increase in tool life by preventing build-upedge formation on the tool and thus the cutting forces could be decreased by about 18 %.…”

In this study tapping operations were carried out using taps of different diameters and with different cutting parameters on AISI 304 austenitic stainless steel. The cutting performances of the taps were determined according to the cutting torques created during the threading and the depth of cut for each cutting feed (Q). With the aid of the obtained experimental data the solution suggestions to the problems in the threading operations for AISI 304 steel were developed. As a result it was specified that the increasing amount of cutting in each pass directly affected the cutting torque. It was determined that there was a tendency to decrease the cutting torque with the increasing depth of cut for each cutting feed. The best tool-life results for an M5 tap were obtained at a 5-mm Q value, whereas for M6 taps it was at a 3-mm Q value. Keywords: tapping, AISI 304, machinability V {tudiji je bilo izvedeno vrezovanje notranjih navojev z uporabo navojnega vreznika z razli~nimi premeri in razli~nimi nivoji vrezovalnih parametrov v avstenitnem jeklu AISI 304. Zmogljivosti vrezovanja navojnih vreznikov so bile dolo~ene glede na moment, ki je nastal med vrezovanjem navojev v globino, za vsako hitrost podajanja pri vrezovanju (Q). S pomo~jo dobljenih eksperimentalnih podatkov so bili postavljeni predlogi re{itev problemov pri postopku vrezovanja navojev pri jeklu AISI 304. Pokazalo se je, da pove~anje vrezovanja pri vsakem prehodu neposredno vpliva na moment pri vrezovanju. Ugotovljeno je, da se zmanj{uje moment vrezovanja s pove~anjem globine reza pri vsakem podajanju pri vrezovanju. Najbolj{a zdr`ljivost orodja pri M5 vrezniku je bila dose`ena pri vrednosti Q = 5 mm, pri vrezniku M6 pa pri vrednosti Q = 3 mm. Klju~ne besede: vrezovanje notranjih navojev, AISI 304, strojna obdelava
