Pre-test

Before you begin this course, test your skills by taking the following assessment to see where you stand. Keep track of your incorrect answers to know which skills you should study. You'll have a chance to take this same practice test again at the end of the course to see how you've improved.

All questions must be answered to submit your assessment.

1. A CNC programmer is machining a part and needs to ensure that all stock is removed, even the stock left from tool deflection. Which of the following options can be enabled to achieve this?

Error: Select an answer

2. A CNC programmer wants to configure a toolpath to descend directly into the part. Which of the following accomplishes this?

Error: Select an answer

3. A CNC programmer wishes to see if the toolpaths applied will leave gouges in a machined part. Which of the following Colorization options allows for this to be shown?

Error: Select an answer

4. A file has two setups, one for the front operation and one for the back operation. Roughing, finishing, and chamfering toolpaths have been applied to both operations. If you wanted to only post the code for the face and the chamfer of the front operation, which of the following would be a valid option?

Error: Select an answer

24. A CNC programmer is creating an NC Program to simultaneously machine the front and rear stations of a part using a dual station vise. They notice that the different tools are being used for the work offsets for both setups, and that the tools are running each work offset sequentially. If they wanted to save time so that both tools are used simultaneously in both setups using one program, what would be an effective option?
