“…TiN and TiCN coated HSS drills under a similar condition produces slightly increased burr height due to the low heat transfer coefficient of coated drills. 21 The machined surface must be smooth for easy handling and easy assembly. If the machined surface is not smooth, then secondary operations like grinding, polishing, and buffing must be done to improve the surface finish.…”

Machining is an inevitable task after processing a material. Among the different materials, fiber-reinforced plastics are used as structural materials in different industries. Compared to conventional materials, fiber-reinforced plastics are less hard by its nature. Due to this reason, the cutting force required during machining a plastic material is lesser than that of other materials. Although the cutting force is less, the influence of other machining parameters on the ease of machining is to be investigated in order to reduce the machining time and cost. Hence, a review on the machining associated successes and failures will be helpful for the manufacturing sectors and researchers in line with the machinability. This review provides a detailed picture of various issues dealt during machining a plastic material. The influences of manufacturing methods on the machinability and machinability measurement methods are comprehensively addressed. In addition, this review also discusses about the influences of machining parameters and optimum conditions for machining. The review also addresses various statistical methods used, machinability enhancement methods adopted, and unconventional methods used in the various researches.

“…On the other hand, there have been very few studies on the machining quality of engineering plastics. [21][22][23][24][25] Besides, the results obtained from the machining of polymer matrix composites may not be applied to the unreinforced polymers. Therefore, researches are still being carried out on the machining of engineering plastics.…”

“…Another machining quality criterion is burr generation during the cutting of plastics. Altan et al 23 reported a study on burr formation during drilling of the engineering plastics. They found that higher feed and lower cutting speed decreased burr height, which was traditionally opposite to that of metal drilling.…”

“…There have been some studies on the hole quality of the drilled plastics. 23,24 In order to determine hole accuracy, there are common equipments for measuring such as coordinate measurement machine (CMM). However, there are some practical measurement techniques that include application of some mathematical approaches, in the absence of the CMM.…”

Engineering plastics have wide applications in different fields of industry due to their light weight and easy shaping. In manufacturing multi-component products, assembly is an inevitable stage and drilling is one of the necessary processes before joining of the components of these products. In this study, two of the most common types of engineering plastics, polyacetal (POM) and cast polyamide (castamide), were drilled with twist drills of 0.5 mm and 1 mm diameters, under different cutting speeds and feeds. In determining the accuracy of the drilled small holes, a mathematical approach was used in which least square circle method was applied and radial error of the each drilled hole was obtained. Thus, the hole accuracy could be determined without measuring equipment such as coordinate measurement machine. It has been seen that POM gave better hole accuracy than cast polyamide due its thermal and tribological properties. The effects of feed and cutting speed on the radial error were also investigated. POM did not show apparent difference in radial error according to the cutting parameters while cast polyamide showed lower radial error in higher feeds with 0.5 mm of drill tool and lower radial error with 1 mm of drill tool. Additionally, the radial error could be reduced with decrease of spindle speed at higher feed.

“…In the given drilling conditions, the hole quality increased at high spindle speed, low feed and drill point angle for both polyamides. Altan and Altan [13] investigated the exit burr height in the drilling of UHMWPE by coated and uncoated HSS (high speed steel) twist drills. The effects of cutting speed, feed, and HSS tool type were determined by Taguchi method.…”

Polymers have been used in various industries and can be produced by forming in the mold but machining operations are usually performed due to needing in the assembly and fixing processes. In particular, drilling of engineering plastics such as polyamide, polyethylene etc. have been investigated by scientists. Additionally, electrically conductive polymers have been developed by adding conductive materials like carbon black, carbon nanotube, graphene etc. to the polymer matrix for electronic applications and automotive industry. For these reasons, this study aims to investigate the effects of drill point angle, feed, and cutting speed on the drill bit temperature by Taguchi and ANOVA (analysis of variance) statistic methods in the drilling of unreinforced polyamide and carbon black reinforced electrically conductive polyamide. In addition, the relation between the drill bit temperature and burr was examined. The optimum drilling condition for minimum drill bit temperature was determined at low cutting speed and drill point angle and high feed for given drilling parameters. It was specified that the drill bit temperature was higher in the drilling of carbon black reinforced polyamide than that measured in the drilling of unreinforced polyamide. The most significant parameter was obtained as the drill point angle by Taguchi method and ANOVA results confirmed this result. Additionally, it was observed that burr formation increased as increasing the drill bit temperature.
