3.3.3.6 PRODUCE A MANUAL GROOVE
3.3.3.6.1 SITUATION
 You wish to visualise the lens thickness and define the curve and the position of the groove.
3.3.3.6.2 PROCEDURE
To produce a manual groove:
1. Load or create a job.
2. Enter its characteristics.
3. Proceed as shown on the flow chart.
3.3.3.6.3 IMPORTANT NOTES
 Only plastics can be grooved.
 The minimum thickness of the lens must be equal to or greater than 1mm to produce a groove.
 The relationship between the minimum Lens face - Groove edge distance and the depth of the groove will
always be adjusted automatically to guarantee the lens resistance.
 To make a groove of any type, the minimum distance between the front face of the lens and the front edge
of the groove (or the rear face and rear edge) must be greater than 0.4 mm. 
If it is less than 0.4 mm at any point of the lens, the groove will not be produced.
3.3.3.6.4 LIMITS
 If the maximum thickness of the lens is less than 2 mm, the applied groove will automatically be of 50%
type, whichever type of groove is selected initially.
 The safety-bevel(s) of a grooved lens will be maintained if the retouch value is less than 0.2 mm to the dia-
meter.
3.3.3.6.5 RETOUCH
 When the edging cycle is finished, remove the lens from the edging chamber without removing the block
so as to be able to retouch it if necessary.
 Check the lens dimensions and finishing.
