Abstract.
Ф40 Ф20 Parts(ф40) 15 Holder Toolpath Fig. 1 Cutting experiment detail drawings Fig. 2 Schematic diagram of simulated cutting and toolpath The CK6136 CNC machine tool is selected, and its parameters are as follow: spindle motor power is 5.5KW, efficiency η=0.75; X-axis/Z-axis servo motor power is 1KW; tool material is carbide YT15; parts material is low carbon steel; cutting processing is in coolant condition.
Because the factors that affect machine tool energy consumption have tool material and shape, workpiece material, machine tool structure, etc, CNC machine energy-saving research needs to take other factors into account comprehensively in next step.

Historically, a multitude of materials and designs have been used in the creation of trademarks
(Per Mollerup 2000) (3) The ceramic mark was a boss mark used in Ancient Rome to identify construction materials such as ceramic titles, bricks, and slates.

It is generally accepted that current strategies for the
resolution of the conventional photolithography may be blocked by optical diffraction and by the
opacity of the materials used for making lenses or supports of photo masks [1].
This phenomenon is similar to the micro-contact problem in Fig. 4, where, by slip-line field theory, the necessary energy and the geometry characteristic of formation mechanism for a material can be predicted.

The forging process is based on the plastic deformation of a material by applying force/pressure to obtain a piece.
As a consequence, the constitutive equations of material change in these areas and as a result the yield stress also varies.
This explains the fact that the material properties in these areas are different from those in other areas of the piece.

Complete removal involves the severance of conductors and removal of jacket structure and platform materials to shore for disposal, reuse or recycling purposes.
In order to reuse any platform facilities, it requires additional considerations with respect to fatigue, material, inspection, removal and reinstallation [14].
