Location choice
(1) the freedom to choose the basic principles of thin
(1) conform to the basic principles. Avoid error matching, easy programming, should choose as a foundation, design and design positioning, positioning, start programming, the three unified consider the best solution. Because when processing positioning and design does not match the mirror, surface treatment and the design and installation for many times, in line with the basic treatment results in an error.

(2) the basic principles of unity. The installation process or more times the choice of location, such as guarantee all surface treatment of the location precision of each other, avoid or reduce the error resulting from the fundamental transformation.
SKF Bearings (http://www.fagbearings-hk.com/) basic principles. Uniform allowance, sorting or finishing process requirement is small, so choose locating datum processing surface as the most basic principle. Such as ZiWei
Convenient charging principle. с choose accurate positioning should ensure database artifacts, convenient and reliable, stable, charging device has simple structure, convenient and flexible operation, and can handle a lot of content.
(5) reduce the knife principle. Batch, workpiece coordinate system determined based on the positioning base of different workpiece coordinate system, that the sword is convenient, sometimes even different knife. Now need to analyze whether the plan can meet the requirements of positioning knife operation, otherwise should reinstall the original set workpiece coordinate system.

(2) crude benchmark choice principle
(1) the principle of the machining surface. To ensure that the surface treatment and surface treatment requirements, no surface treatment for coarse base between this position.
(2) allowance minimum principle. Surface machining allowance minimum as the basic rough surface treatment, to ensure that all enough allowance.
Important principles = surface. Ensure that important surface uniform allowance, should choose rough surface processing base.
Don't reuse х principle. Without surface treatment of crude benchmark and low accuracy of coarser, second, installed in the machine (or equipment) can truly first may not be as wrong positions, related to large local errors due to surface treatment. Usually thick foundation, therefore, should not be reused

(5) the workpiece loading principle. Such as a large base, the surface level off is smooth, no burr requirement, profits, gate or other defects, in order to accurately locate workpiece is reliable.
