9.2.6 Read curve table values (CTABTSV, CTABTEV, CTABTSP, CTABTEP,
CTABSSV, CTABSEV, CTAB, CTABINV, CTABTMIN, CTABTMAX)
Function
The following curve table values can be read in the part program:
● Following axis and leading axis values at the start and end of a curve table
● Following axis values at the start and end of a curve segment
● Following axis value for a leading axis value
● Leading axis value for a following axis value
● Following axis minimum and maximum values
– In the entire definition range of the curve table
or
– In a defined curve table interval
Syntax
CTABTSV(<n>,<gradient>[,<following axis>])
CTABTEV(<n>,<gradient>[,<following axis>])
CTABTSP(<n>,<gradient>[,<leading axis>])
CTABTEP(<n>,<gradient>[,<leading axis>])
CTABSSV(<master value>,<n>,<gradient>[,<following axis>])
CTABSEV(<master value>,<n>,<gradient>[,<following axis>])
CTAB(<master value>,<n>,<gradient>[,<following axis>,<leading axis>]
CTABINV(<following value>,<approximate
value>,<n>,<gradient>[,<following axis>,<leading axis>]
CTABTMIN(<n>[,<following axis>])
CTABTMAX(<n>[,<following axis>])
CTABTMIN(<n>,<a>,<b>[,<following axis>,<leading axis>])
CTABTMAX(<n>,<a>,<b>[,<following axis>,<leading axis>])
Meaning
CTABTSV: Read following axis value at the start of curve table no. <n>
CTABTEV: Read following axis value at the end of curve table no. <n>
CTABTSP: Read leading axis value at the start of curve table no. <n>
CTABTEP: Read leading axis value at the end of curve table no. <n>
CTABSSV: Read following axis value at the start of the curve segment
belonging to the specified leading axis value (
<master value>)
CTABSEV: Read following axis value at the end of the curve segment
belonging to the specified leading axis value (
<master value>)
CTAB: Read following axis value for specified leading axis value (<master
value>
)
CTABINV: Read leading axis value for specified following axis value
(
<following value>)
