Reference allowance of finishing in radial

Program type M
Conditions Immediate
E4
Unit 0.1 mm/0.01 inch
Setting range 0 to 999
The reference value of each finishing allowance R (
FIN-R) which is
automatically set when the roughness levels of the line- or face-machining
units have been set
The finishing allowance R in the case of roughness level 4 becomes the
value of this parameter, and the values for all other roughness levels are
calculated using the expressions listed in the table below.
Element used to set the cutting start point
and escape point (the second clearance)
Program type M
Conditions Immediate
E5
Unit 0.1 mm/0.01 inch
Setting range 0 to 999
Element used to set the cutting start point and escape point (the second
clearance)
E2 is used generally as a clearance on the X-Y plane, however, E5 is used
when the condition meets both of 1) and 2) mentioned below.
1) There is pre-machining in the same unit.
2) The parameter (
E91 to E95) that makes E5 effective is set to ON (1).
[Applicable units]
LINE OUT, LINE IN, STEP, POCKET, POCKT MT, PCKT VLY
[Related parameters]
E91 bit 3, E92 bit 3, E93 bit 3, E94 bit 3, E95 bit 7
* Parameter that effectuates
E5 in the applicable unit.
Reference allowance of finishing in axial
direction
Program type M
Conditions Immediate
E6
Unit 0.1 mm/0.01 inch
Setting range 0 to 999
The reference value of each finishing allowance Z (
FIN-Z) which is
automatically set when the roughness levels of the line- or face-machining
units have been set
The finishing allowance Z in the case of roughness level 4 becomes the
value of this parameter, and the values for all other roughness levels are
calculated using the expressions listed in the table below.
