Introduction
Titanium matrix composites (TMC) have higher specific stiffness/strength, higher wear/corrosion resistance, higher anti-fatigue performance and better high-temperature properties, which are recognized as one of the new materials to replace titanium alloys.
Experimental Work Materials and Machine Tools.
The machined materials in the experiments were vol.(5-8)% TiCp/TC4 composites which were produced through vacuum self-consuming electro-arc melting and hot forging technology.

In this approach, neither adding nor removing materials.
In some cases, powder or sheets materials are used to replace that of liquid.
Main limit is that the materials can be synthesized again by solution.
In this case, the most materials can be processed.

Skid steer loader shovel action features combined with advantages of the shovel method of cooperation, we design the trajectory of shovel as follows:
(1) In the line segment shown in the Figure,the boom and bucket keeps still ,the bucket bottom and the bottom of the material maintain Figure 1.Schematic diagram of coordinate
level, the whole machine maintains a uniform speed frame of working devices
of inserting into the stockpile to the A point;
(2) In curve segment shown in the Figure, the whole machine maintains a uniform speed of progress at, the boom keeps upgrading and bucket keeps turning to complete the setting track.
Tracking curve and error curve of shovel track In Fig.5 and Fig.6, 1mm amplitude jitter occurs in 0.625s, the boom and bucket cylinder being in contact with the material since 0.625s accounts for this happening , sudden loading exerts certain shock on the hydraulic system.
