Quality-Assurance Inspection
The technique of quality-assurance inspection is the measuring of the various quality characteristics generated in a production process or inherent in the material.This type of inspection can be a check made on each piece produced or a check made on a statistical sample of the lot.The inspection may be a mechanical or electronic measurement or visual inspection the result of which are compared with standards.
The inspection can be performed be the operator or worker making the part or component by a second person who is responsible for measuring only or performed entirely by computer-controlled measurement.
The inspection assures that the products being produced meet the standards of quality and quality levels which have been previously established.

M Code
The M code has various uses.Usually the meaning of M codes vary with the NC machines of different manufacturers.The selected M codes are used for the Cadillac NC-300 milling machine with the FANUC 6MB controller system.

T Code
Two or four digits can be specified after the address T,depending on the design of the NC machine.On the Cadillac NC-100 lathe with the FANUC 6T controller system,four digits can be specified.The first two digits represent the turret position or tool number and the last two digits,the offset number.

The Coordinate System for NC Machine
A coordinate system should be defined before a motion statement is specified.On an NC machine, the directions of the coordinate axes are fixed.However,the origin of the coordinate system can be set at any desired position.A cutter motion can be corretly defined only after the origin of the coordinate system has been set at the right position.The code G92 is used to define the origin of a coordinate system with the following format

ReplyDeleteyou defined quality assurance but i want to definition of "Quality Assurance Inspection" that is a process control engineering technique. you should define this term or else you wont get any point.
clue: you can use this source.
