Lock Axis
LOCKY
This expression does not need to be added as a ude. You can select the processing method from Axis Control>Rotary Axis Control>Rotation Type in Mastercam.
Type of UDE:
It is a standard type UDE. In standard usage, there is no need to make an extra definition in MANUSpost developer to activate this UDE. However, if desired, UDE can be defined in the CAM settings section of MANUSpost developer (can also be defined as “Custom UDE”). In this case, the user can make extra customizations in this UDE, create and use “Event”, “Script”, “Command” connected to the UDE.
What Is It Used For?:
It is the UDE that is used to activate the Polar mode, and with this UDE one of the linear axes (usually the Y-axis) is locked (or deactivated), allowing the machining to be processed using the other linear axis (X-axis) and the rotary table C-axis.
Polar mode is a special mode used only in 3-axis milling operations.
This mode is activated when motion limits prevent machining in the machine X and/or Y axes.
Polar mode is a very common mode in mill-turn machines.
When this mod is activated:
Y axis is automatically disabled in mill-turn machines, machining is performed by using +X and C axis instead of Y axis, that is, by continuously rotating the part in C axis. Mill-turn machines usually have a command that activates this mode ( G12.1 / G112 / TRASNMIT etc.)
Although there is no special command that activates this mode on milling machines, this mode can also be used in 5-axis milling machines. Thanks to a special structure called “Parametric Polar Mode”, MANUSpost Developer allows you to use polar mode in your multi-axis milling machines. When you use it on milling machines, you can also choose to lock the X axis instead of Y and manage the process from the Developer kinematics settings. When one axis is locked, the operation is performed using the other linear axis and the C axis.
In 5-axis milling machines, the locked axis is selected as the axis with short mobility, that is, the axis with the axis limit problem.
In case of limited mobility of both X and Y axis in 5-axis milling machines, MANUSpost Developer has the flexibility to enable any diagonal axis with scripts and variables.
Since the MCS in 5-axis milling machines is mostly not in the center of the table, your CNC machine must have TCPC feature to perform this operation, a parametric solution must be produced for the machines without TCPC feature.
Some of the mill-turn machines may not have Polar codes (G12.1 / G112 / TRANSMIT) or their use may be problematic. In such cases, you can use the special parametric polar mode of MANUSpost Developer.
You can watch the related videos to get detailed information about the use of polar mode and parametric polar mode in milling and mill-turn machines.
How to Deactivate?:
When this ude is activated, it affects all subsequent operations. You can use the UDE below to deactivate it.
UNLOCKY
You can cancel the machining by selecting No Rotation from Axis Control>Rotary Axis Control>Rotation Type in Mastercam and locking the axis.
What Affects/Changes in MANUSpost Developer:
When this UDE is activated, the “VAR.State.OpPolar” variable becomes active (True) and the “OpPolar” operation type is added to the operation tree and the kinematics and “Commands” that are desired to work in this operation type are defined here.
