## Overview

Reflecting the latest technology and tools of the trade, MATHEMATICS FOR MACHINE TECHNOLOGY, 7e provides the mathematical skills and practice that students and apprentices will use on the job in the machine trades and manufacturing fields. This comprehensive book combines math concepts with relevant machine applications through industry-specific examples, realistic illustrations, and actual machine applications. Problems and examples progress from simpler to more complex, from general math to trigonometry and solid geometry. The examples and problems relate directly to how the math is used in machine trades and manufacturing fields and include calculator operations where appropriate. In addition, the exciting new Seventh Edition includes all-new units on electronic calipers, height gages, and electronic micrometers, as well as thorough coverage of measuring in both metric and customary systems. This proven text continues to provide readers with practical vocational and technical applications of mathematical concepts necessary to excel in the machine, tool-and-die, and tool design industry.

- All-new units cover measuring with metric calipers and height gages (Unit 30) and micrometers (Unit 33), ensuring your students have a solid understanding of the metric system, including converting within the metric system, converting between the customary and metric systems, and using metric measuring instruments.
- All-new units on electronic calipers and height gages (Unit 31) and electronic micrometers (Unit 34) demonstrate step by step how to use the electronic measuring instruments in both customary and metric units.
- Most sets of exercises begin with six "Tooling Up" exercises that use concepts from earlier units. Included in each unit except for Unit 1 and the Achievement Review unit at the end of each section, these hands-on applications help students retain ideas from previous sections and continue to build on their knowledge.

- An expansive Instructor's e-resource includes answers and solutions to all problems.
- Ensuring your students are well prepared for real-world practice, the text provides thorough coverage of the emerging electronic and digital tools while also retaining instructions for using analog tools.
- MATHEMATICS FOR MACHINE TECHNOLOGY, 7e provides general math as well as more advanced topics like compound angles and numerical control.
- The text delivers thorough coverage of polar coordinates and hexadecimal and BCD (Binary Coded Decimal) numeration systems as well as detailed material conversion between metric and customary systems of measure.
- Comprehensive scientific calculator examples are up to date, while sequencing is completely modernized and includes up-to-the-minute instructions on how to use this tool.
- Problems and examples reinforce the book's student-friendly method of progressing from the simple to the relatively complex, underscoring its organized approach to learning.
- Extensive use of realistic trade-related illustrations bring concepts to life.
- Offering an up-close, realistic experience for what's required in the industry, the text emphasizes an analytical approach that is necessary in translating engineering drawing dimensions to machine-working dimensions.
