This text describes the data presented in the paper: Micro-machinability of nanoparticle-reinforced Mg-based MMCs: An experimental investigation 

========================
Introductory information
========================
Files included in the data deposit (include a short description of what data are contained): 

1)machining parameter set data
2)machined surface topography data
3)surface roughness measurement data


Explain the relationship between multiple data sets, if required:

n/a

Key words used to describe the data:
metal matrix composites (MMCs), micro-machinability, surface roughness, surface topography, size effects


========================== 
Methodological information
==========================
A brief method description – what the data is, how and why it was collected or created, and how it was processed:

Surface topography data were collected by SEM – data were not post-processed; surface roughness data were collected using surface profilometer – data were processed using ANOVA tool in Minitab package.
All these data were used to analyse micro-machinability of nanoparticle-reinforced Mg-based MMCs.


Instruments, hardware and software used: 

Scanning Electron Microscope (TM3030); Zygo surface profilometer (NewView 5000) and MiniTab

Date(s) of data collection: 

Feb - May 2015
