Yes, I am familiar with using a vernier caliper to measure job dimensions.

• To measure a job using a vernier caliper, first ensure that the caliper is zeroed out and the jaws are clean.

• Place the job between the jaws of the caliper and gently close them until they are snug against the job.

• Read the measurement on the scale of the caliper, taking note of the units being used (usually millimeters or inches).

• For more precise measurements, use the vernier scale on the caliper to read...read more

• I have experience reading technical drawings and blueprints.

• I am familiar with symbols, dimensions, and tolerances used in drawings.

• I can interpret different views and sections in a drawing.

• I understand the importance of accuracy and attention to detail when reading drawings.

• I have successfully operated VMC machines based on drawings provided.

5S is a workplace organization method that stands for Sort, Set in Order, Shine, Standardize, and Sustain.

• Sort: Remove unnecessary items from the workplace

• Set in Order: Organize the remaining items in a logical and efficient manner

• Shine: Clean and maintain the workplace regularly

• Standardize: Establish procedures and guidelines for maintaining the workplace

• Sustain: Continuously improve and maintain the 5S system

The least count of a vernier caliper is typically 0.02 mm or 0.001 inches.

• The least count is the smallest measurement that can be read on the scale of the vernier caliper.

• For metric vernier calipers, the least count is usually 0.02 mm.

• For imperial vernier calipers, the least count is typically 0.001 inches.
