Researcher | Synthetic Fiber | Matrix | Operating Parameters | Findings |
Hocheng and Tsao [91] | Woven Glass fiber | Epoxy | · Feed rate · Spindle speed · Drill diameter | · Ra increased with an increased cutting feed rate · No obvious effect of cutting speed |
Palanikumar [106] | Glass fiber | Epoxy | · cutting speed · Fiber orientation · depth of cut · Feed rate | · Ra decreased as cutting speed and depth of cut increased · Ra increased as feed rate and the fiber orientation increased |
Khashaba, El-Sonbaty [93] | Woven Glass fiber | Epoxy | · Feed rate · Spindle speed · Drill diameter | · Ra increased with increasing the cutting feed · no clear effect of cutting speed |
Kini and Chincholkar [94] | Glass fiber | Polymer | · Feed rate · Spindle speed · Depth of cut | · Large values of Ra recorded at low feed rates · Feed rate is most effective factor |
