Tool radius compensation (G41, G42) and I, J, K command (I, J type vector command)
By commanding tool radius compensation (G41, G42) and "I, J, K" in the same block, the direction of compensation can be
changed at will. An example using "I, J type vector (G17 plane)" is used to describe the vector created by tool radius
compensation commands (G41, G42).
"I, J type vector" does not calculate the intersection of the programmed path. Instead, the compensation vector is found by
compensating the compensation amount perpendicular to the direction specified by "I, J". The I, J vector can be commanded
at the start of compensation or during compensation mode. The compensation amount is determined by the compensation
No. (modal data) of the block where I, J are specified.
■Commanding "I, J" at compensation start
: Program path,
: Tool center path
• With a movement command
I, J type vector
When "I, J" is commanded
When "I, J" is not commanded (type A)
• No movement command
I, J type vector
When "I, J" is commanded
When "I, J" is not commanded (type A)
