When Park with titanium wire without heat. Roughness increases equal to 17.37 nm when heating the specimen found that roughness is higher up again. If the oven is equal to 23.74 nm are blowing hot air for 5 minutes, close to the workpiece is not heated, but after 10 minutes, the roughness of the workpiece to a higher value, but returned. tends to decrease as the time to add time to blow hot air up probably because of the heat in a long time, causing the particle film is tight, the higher the roughness of the surface is reduced.
