Machining is a process that accurate to
remove material by mechanical machining technology.
The main classification:
Step of working out process regulations:
1) Calculating annual
production program, determine the type of manufacture.
2) Analysis part drawing
and the product assembly drawing.
3) Select blank.
4) Formulation process
route.
5) Determine the
machining allowance of each process, calculating the dimension and tolerance.
6) Identify the equipment
used in each process and cutting tool, jig, measuring tools and auxiliary
tools.
7) Determine the cutting
dosage and man-hour quota.
8) Determine the main
process of technical requirements and test methods.
9) Fill in the process
documents.

Two sources familiar with the plan said that Daimler hopes to buy a part of the rights of a Chinese automotive company, Beijing Automotive, to increase its share of the Chinese market.
"The investment will be conducted before the BAIC Motor's initial public offering (IPO) and Daimler will become the only anchoring investor in the automotive industry." One source said.
According to sources, Beijing Automotive Group plans to list Beijing Auto in late 2013 or 2014. Daimler may purchase approximately 10% of its equity interest in Beijing Auto before listing, and thus gain greater access to the Chinese market.
"If IPO stocks rise, Daimler will benefit," the source said.
Daimler is also seeking to obtain a board seat at Beijing Motors, but the discussion on the issue is not yet over, the person said.
Daimler declined to comment; it could not be immediately contacted by BAIC to comment.
Mechanical processing have manual processing
and CNC machining two types. Manual processing is means machining
various materials by mechanical workers manual milling machine, lathe,
drilling machine and the sawing machine and other mechanical
equipment. Manual processing is suitable for small batch production,
simple parts. Numerical control machining (CNC) means the mechanical
workers use numerical control equipment, the CNC equipment including CNC
center, milling center, wire cutting equipment, thread cutting machine,
etc. The vast majority of the machining shop machining the parts by
numerical control machining technology. Through programming,
coordinates the parts in the Cartesian coordinate system (X, Y, Z) into a
programming language, the CNC controller of numerical control machine by
identifying and explain programming language to control the axis of CNC machine
tools, automatic removal of material, get the part according to the requirement
and finish machining. CNC machining in a way that is straight artifacts, suitable for
mass and complex shape parts.
