Abstract
This paper presents an experimental investigation of deep hole drilling using CNC milling machine. This experiment investigates the effect of machining parameters which are spindle speed, feed rate and depth of hole using minimum quantity lubricant on the roundness error. The experiment was designed using two level full factorial with four center point. Finally, the machining parameters were optimized in obtaining the minimum value of roundness error. The minimum value of roundness error for deep hole drilling is 0.0266 at the spindle speed is 800 rpm, feed rate is 60 mm/min, depth of hole is 70 mm and minimum quantity lubricant is 30ml/hr.
Highlights
The demands in industrial nowadays need for the application of machining process to produce a particular product compared to the use of manpower in the past
By its desire to meet the needs and demands of the present time, non-conventional machining or modern machining was introduced as abrasive water jet (AWJ) [8, 9], electrochemical machining (ECM) [10, 11], electric beam machining (EBM) [12, 13] and etc
It was found that minimum roundness error obtained at hole 20
Summary
The demands in industrial nowadays need for the application of machining process to produce a particular product compared to the use of manpower in the past. Various types of machines have been introduced so far. Prior conventional machining was applied as turning [1, 2], milling [3, 4] drilling [5, 6], grinding [7] and so on. Each machining process applied is based on the products to be produced. For the production of deep holes, a particular machining process is needed namely deep hole drilling
