Description
Channel-specific diameter programming DIAMCHANA[AX], DIAMCHAN
The DIAMCHANA[AX] or DIAMCHAN statement causes the specified axis or all the
transverse axes associated with axis-specific diameter programming to adopt the active
status of channel-specific diameter programming. These axes will subsequently be subject to
channel-specific diameter programming.
Axis-specific, non-modal/action-based diameter programming DAC, DIC, RAC, RIC
The statements define the dimension type non-modally in terms of either a radius or a
diameter value. The modal status of diameter programming, e.g., for display or system
variable purposes, remains unaffected by this.
These statements are permissible for any commands for which channel-specific diameter
programming is relevant:
• Axis position: X..., POS, POSA
• Oscillating: OSP1, OSP2, OSS, OSE, POSP
• Interpolation parameters: I, J, K
• Contour definition: Straight line with specified angle
• Rapid retraction: POLF[AX]
• Movement in tool direction: MOVT
• Smooth approach and retraction:
