Abstract: This paper describes design of a prototype of a wire-sawing machine and some machining demonstrations. Slicing the rock samples is preferable to observe their interior for in-situ analysis in lunar and planetary explorations. The requirements for the wire-sawing machine were clarified as follows: using a long saw wire to extend the duty cycle, and winding and unwinding the saw wire with two reels. After building a prototype of the wire-sawing machine, the cutting performance in vacuum was compared with that in… Show more

Future lunar, planetary, and asteroid exploration will strongly demandin situanalysis of rock samples to obtain data related to various aspects. For precise composition analysis, a sample surface should be smoothed. In this paper, a surface shaver with a piezoelectric actuator is proposed and its machining performance in air is investigated. Shaving teeth are mounted at the ends of a pair of lever mechanisms. The device is pressed through four springs onto the workpiece with a linear actuator. When a sinusoidal voltage of 50 Vp-pand an offset voltage of 25 V were applied, the resonance frequency was 556 Hz and the unloaded amplitude of the shaving teeth was 0.77 mmp-p. Basalt workpieces were machined for 10 min in air. Increasing the thrust force reduced the surface roughness, although the amount removed diminished with a further increase in the thrust force. The surface roughness varied widely not only due to the amount removed but also due to containing the pores.

Three huge vertical holes have been found on the Moon and their scientific explorations are planned by the UZUME (Unprecedented Zipangu (Japan) Underworld of the Moon Exploration) Project. For such explorations, a rover with large wheels is preferred for climbing over bumps. However, the exhaust materials from landers or rovers should be avoided to prevent contamination of the terrain. This paper proposes a rover with inflatable tubes that function as outer wheels. A prototype with one degree of freedom was built. The inflatable wheel was 1000 mm in diameter and 400 mm in width, and weighed 2.0 kg. A small cart, which was used as a weight, was moved on the torus to revolute the rover. Each cart weighed 0.5 kg. The performance of the rover was tested and compared with the calculated results. The climbable step height and slope angle were statistically calculated and were independent of gravity. The climbable step height and slope angle were 15 mm and 9°, and they almost agreed with the calculated results.

This paper deals with a percussive rock surface crusher driven with a solenoid to smoothen the sample surface by a 2-axis planar motion. The weathered rock surface should be removed and smoothened before analyzing its structure and composition precisely. The solenoid, which generates a large vibration amplitude and a large impulsive force, was used to vibrate a tool bit with engineered 1-mm pyramids made of tungsten carbide. The tool bit was fixed parallel to the feed direction or with a skew. A rock sample was moved by a stage with movable ranges for the machining of 10 mm and 20 mm in the x- and y-directions, respectively. The sample paths were randomly generated in 1 or 2 directions. In the comparisons of the surface roughness, the 2-axis motion and tool skew not only allowed isotropic and small roughness but also the removal of more amount due to the removed debris. The roughness reached several tens of micrometers without a certain special frequency component. This level allows for component analysis by X-ray fluorescence or laser-induced breakdown spectrometer.
