2. Description of Experiment
The main objective of the work is to establish a relation between cutting speed,
feed and depth of cut on SR. AISI316 and AISI410 materials are taken as the
work piece materials for all trials with diameter of 32 mm and machined length of
60 mm. The chemical composition of the work materials are given in Table 1.
The work piece material’s qualities are confirmed to grade AISI316 and AISI410.
The experiments are conducted in Fanuc CNC lathe. A work piece positioning
accuracy is ± 0.010 and run out is tested by dial gauge heavy duty magnetic base.
The range of cutting parameters is selected based on tool manufactures
handbook (Tungaloy Cutting Tool Co., Ltd). In this investigation, three types of
cutting inserts are taken for turning process. Multi-layered CNMG 120408 coated
with TiCN/Al2O3 of 14 μm, multi-layered CNMG 120408 coated with Ti(C,N,B)
of 6μm and single-layered CNMG 120408 coated with TiAlN of 3 μm. Tool
holder of PC LNR 25 × 25 M12.1 was selected for all trials. SR is measured in all
trials by the SURF TEST 211 and it is denoted by Ra. Measurements are taken by
the proper setting of work pieces and the instrument. In the present work, three
parameters each set at three levels are chosen for experimentation.
