Surface roughness CONFIGURATION SYMBOL BY ISO 1302 - 1978 By Budi Maryanto , ST

A.  PURPOSE surface roughness CONFIGURATION SYMBOL BY ISO 1302-1978

The purpose of surface roughness symbol configuration according to ISO 1302 - 1978 in the working drawings, is to declare
1. the level of surface roughness, in states with a level surface with a 
    roughness value of N 1 to N 12
2. direction of former penggerjaan as a result of the production 
   process on the workpiece, denoted by the symbol towards the 
   former work
3. coating on the workpiece as the end result of a product that aims to
   increase the added value of an existing product, is expressed by writing the type of coating, or production processes used

Configuration of the surface roughness symbol

Given the configuration of the surface roughness symbol on the working drawings are forwarded to the production process can determine the selling price of a product, thus increasing the company's profit after the cost of doing the calculation on the entire production process.
  Giving Coat surface roughness configuration according to ISO 1302 - 1978 in the working drawings, can provide clear guidance directed, and coordinated well on the production process, at the time of the end of a product.

B. ROLE IN AUTO CAD surface roughness GIVING BY CONFIGURATION SYMBOL ISO 1302 - 1978

AUTO CAD program one of the program that is used for drawing techniques provide an important role in the provision symbol penyeleseian configuration problem of surface roughness.
By drawing the symbol configuration complete surface roughness as a whole, and then store it in the template in AUTO CAD Program, and call him back when we drew with AUTO CAD Program by:










1. click the INSERT
2. Click LAY OUT FORM TEMPLATE
3. Select the configuration Coat surface roughness in accordance with the working drawings.
This can save time when we draw with AUTO CAD.
