Design and manufacturability data of automatic lotus fiber extractor

Lotus silk is a type of textile and is considered as one of the most expensive fabrics in the world. It is made by weaving lotus fibres which are popularly extracted from lotus stems in some Asian countries such as Vietnam, Myanmar, Cambodia, etc. This dataset consists of the design and manufacturability data for automatic lotus fiber extraction machine including three modules (1) workpiece feeding, (2) fibre pulling, and (3) fibre spinning. The diagram of the machine principle is built in AutoCad while the 3D model was designed in Solidworks and some parts were collected from open-source library such as MISUMI, GrabCAD, and AIRTAC. The connection diagram for the HMI is designed in AutoCad and the PLC program is constructed in TIA portal. In addition, the manufacturing cost is also provided for a purpose of reference if the other researchers are interested in developing this machine. This dataset consists of (1) diagram of principle, (2) the CAD file for the design, (3) the pdf file for the connection diagram of the HMI and the PLC program, and (4) the manufacturing cost excel file. This dataset has the potential to promote the future innovations that improves the productivity of lotus fibre extraction process and working environment of the labours.


Value of the Data
• This data can be used by the manufacturer to fabricate the lotus fiber extraction machine.
• Designers, engineers, and researchers can use these data as reference when developing the new design of fiber extracting mechanism.• The other researchers may reuse this data as a starting point to improve the design of the automatic lotus fiber extraction machine.Many design parameters need to be optimized to enhance the efficiency of the machine.

Background
These data add the information in more details of design of the lotus fiber extracting machine to the previous paper [ 1 ] such as overall principle of operation, design parameters, control system and materials.In addition, these data additionally provide an estimated manufacturing cost to the other researchers before manufacturing decision-making.

Data Description
The data consists of four components: (1) CAD files in .DWG file format: The computer-aided design file of machine principle have been included.This file describes the diagram of linkage that expresses the transmission system of the machine.(2) CAD files in .partfile format: The computer-aided design file of the whole machine structure has been included in.SLDASM, namely machine.SLDASM.For designs of components, a CAD file for each component has been included in.SLDPRT.

Experimental Design, Materials and Methods
This dataset comprises four components that were generated as discussed next.
(1) 2D CAD data: The 2D CAD data is manually designed in AutoCad2018.
(2) 3D CAD data: The 3D CAD data was manually collected from open-source websites and online repositories.Specifically, we searched through websites such as MISUMI, GrabCAD, and AIRTAC.We used the following keywords in our search: (1) 'motor', (2) 'Spring Washers,' (3) 'Aluminum Extrusion,' and ( 4) 'air gripper.'A summary of the designs gathered, and the corresponding sources and attributions are presented in Table 1 .Additionally, we referenced each source throughout our research to keep up to date with the latest versions of each design.(3) Connection and ladder diagrams for the HMI and the PLCs: The connection diagram for the HMI is manually designed in AutoCad2018.The ladder diagrams for the PLCs is built up in TIA portal V15. ( 4) Manufacturing cost: The manufacturing cost of the automatic lotus fiber extraction machine is built up by the authors which is summary of the price of the used devices and the machining cost.The machining cost is determined by the costing tool of SolidWorks.The material of the machine is aluminum 6063-T5 which has the density of 2,7g/cm 3 , the machining cost for each kilogram of aluminum was assumed to be $10 and the material cost was added to obtain the total cost of the machined parts.The 3D printing cost is calculated by multiplying the printing cost for each hour and the total 3D printing time in which the printing cost is assumed to be $8 per hour for ABS material, the 3D printing time is estimated by Ultimaker Cura software V5.0 with infill density of 50 %.
