These tutorials will show you how to use locating pins and guides. The first tutorial will describe the principles of positioning, and will be followed by examples of the application of locating pins and guides

(1) Principles of positioning

	1.	What is positioning?... Positioning means maintaining a positional relationship between two objects with a high degree of precision. Either object: Serves as a locating base... (Example: Locating jig) The other object: The object to be positioned onto the locating base... (Example: Workpiece)
	2.	Place two objects in a configuration where their positional relationship is set in an effective manner (refer to [Fig. 1]). Example: 1) Keep two dowel pins for positioning as far apart from each other as possible 2) Set the dowel pins in symmetrical positions
	3.	Position the workpiece using three-directional constraint. (Four-directional constraint makes it impossible to insert or eject the part.)
	4.	Select a positioning method based on the operation to be carried out (manual, automatic, prototyping, mass production, etc.) and the features (precision level, appearance quality level, material, etc.) of the workpiece.
	5.	Do not fail to take measures against deteriorations in positioning performance due to wear or deformation.

(2) A variety of positioning methods

Positioning methods are classified as shown below (refer to [Fig. 2]).
