2、多选题：
When programming for unicycle wheel machining, which of the following factors must be considered to ensure successful operation?
选项：
A:The rotational symmetry of the unicycle wheel must be accounted for in tool path planning.
B:Tool length compensation is irrelevant for unicycle wheel machining due to its simple geometry.
C:Material properties such as hardness and thermal conductivity influence cutting parameters.
D:Multiple clamping operations may be required to machine all features of the wheel.
E:Surface finish requirements dictate the selection of appropriate cutting tools and speeds.
答案: 【The rotational symmetry of the unicycle wheel must be accounted for in tool path planning.;

3、判断题：
The G68/G69 instructions in CNC milling programming can only be applied to rotational symmetric parts, as their primary function is limited to simplifying programming for such geometries.
选项：
A:错
B:对
答案: 【错】

A:G00 - Rapid positioning
B:F100 - Feed rate
C:M00 - Program stop
D:T01 - Tool selection
答案: 【G00 - Rapid positioning】

5、判断题：
G00 in FANUC CNC milling programming is used for rapid positioning, not for actual cutting operations.
选项：
A:对
B:错
答案: 【对】
