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
