Brief Description
Types of feedrate
The feedrate determines the machining speed (axis or path velocity) and is observed in
every type of interpolation, even where allowance is made for tool offsets on the contour or
on the tool center point path (depending on G commands).
The following types of feedrate allow optimum adaptation to the various technological
applications (turning, milling, drilling, etc.):
• Rapid traverse feedrate (G0)
• Inverse-time feedrate (G93)
• Linear feedrate (G94)
• Revolutional feedrate (G95)
• Constant cutting rate (G96, G961)
• Constant speed (G97, G971)
• Feedrate with thread cutting (G33, G34, G35)
• Feedrate for tapping with compensating chuck (G63)
• Feedrate for rigid tapping (G331, G332)
• Feedrate for chamfer/rounding FRC, FRCM
• Non-modal feedrate FB
Programmable run-in/run-out path for G33
The thread run-in and run-out paths can be programmed. The thread axis is accelerated and
decelerated within the defined distance.
Note
If a very short distance is specified, the axis can be overloaded.
